Genetics

 

Genetics

DEFINITION:

Genetics is the study of how genes work and how they behave. Genes are molecular instructions made up of DNA (deoxyribonucleic acid) that are found inside the cells of all organisms, from bacteria to humans. Genes, which are found in one or more chromosomes, determine an organism's characteristics, or traits. The genome is the collection of all of an organism's genes. To put it another way, the genome is divided into chromosomes, which contain genes, which are formed from DNA.

EXPLANATION:

Geneticists want to know how cells use and govern the information encoded in genes, as well as how it is passed down from generation to generation. They also look into how minor genetic differences might affect an organism's development or cause disease. Classical genetics refers to genetic approaches and procedures that predate the development of molecular genetics, which investigates the structure and function of genes at the molecular level. Classical genetics is primarily concerned with the way by which genetic features are transmitted in plants and animals, and it remains the foundation for all other issues in genetics. These traits are classed as dominant (always expressed), recessive (subordinate to a dominant trait), intermediate (partially expressed), or polygenic (either expressed or not expressed) (due to multiple genes). Furthermore, the features are either sex-linked (due to the action of a gene on one of the sex chromosomes) or autosomal (due to the action of a gene on one of the sex chromosomes) (result from the action of a gene on a chromosome other than a sex chromosome). Gregor Mendel, an Austrian monk, pioneered classical genetics by tracing the inheritance patterns of specific features in pea plants and demonstrating that they could be quantitatively expressed ("Mendel's laws"). Experiments on Plant Hybridization, Mendel's 1865 article, went mostly overlooked until the early twentieth century. The inheritance patterns discovered by Mendel are currently used in the study of genetic illnesses.

Molecular genetics uses genetics and molecular biology tools to study the development, structure, and function of macromolecules that are necessary to live (such as nucleic acids and proteins), as well as their role in cell replication and genetic information transfer. The revelation of the structure of DNA by James Watson and Francis Crick in 1953 considerably expanded the research options available to geneticists. In the 1970s, scientists were able to start sequencing genes (determining the exact order of the four subunits of DNA — adenine, guanine, cytosine, and thymine); cloning genes (producing a replica of a gene from one organism), and moving genes from one organism to another to create genetically modified organisms thanks to the discovery of restriction enzymes (which catalyze the cleavage of DNA at specific sites to produce discrete fragments) (GMOs). Recombinant DNA technology or genetic engineering refers to the combination of the two methods.

GENETICS SUBDISCIPLINES

Genetics of Populations, Quantitative Genetics, and Ecological Genetics

Population genetics, quantitative genetics, and ecological genetics are all subfields of classical genetics (supplemented with modern molecular genetics). Though they all investigate populations of species, their focus differs slightly. Natural selection, mutations, and migration all influence the distribution of genes, and population genetics analyses how their frequencies change as a result of these influences. Quantitative genetics is the study of continuous traits (such as height or weight) that do not exhibit straightforward Mendelian inheritance because they are the product of the interplay of many different genres. It is based on population genetics. Ecological genetics builds on the fundamental ideas of population genetics, but it is more specifically focused on ecological challenges, such as the link between species and their surrounding environments.

Medical Genetics

The application of genetics to medicine is known as medical genetics. Clinical genetics (the diagnosis and treatment of genetic illnesses), cytogenetics (the study of chromosomes under a microscope), molecular genetics, and genetic counseling are all examples of medical genetics (education and guidance offered by professional advisors to help people make informed decisions based on personal genetic information).

Genetics of Behavior

Behavioral genetics is the study of how heredity influences animal behavior. Behavioral genetics is the study of the genetic foundation of personality as well as the causes and effects of human problems like mental illness, substance misuse, violence, and social attitudes in humans.

Genomics

Genomics is the study of large-scale genetic patterns across a species' genome. The data obtained from genome sequence data also indicates what genes perform, how they're controlled, and how they interact. The Human Genome Project, which is now complete, has developed a genetic blueprint for creating a human person. Researchers will be able to use this crucial knowledge to find the genetic contributions to diseases, build highly effective diagnostic tools and therapies, and better understand people's health requirements based on their genetic makeup.

FORENSIC SCIENCE

FORENSIC SCIENCE

DEFINITION:

Forensic science is the study of a wide range of sciences to answer problems in the legal system. In a variety of sectors, forensic science employs cutting-edge technology to unearth scientific evidence.

EXPLANATION:

The term "forensic" is derived from the Latin word "forensics," which means "used in or suited for courts of justice or public discussion or debate." Forensic science is any science that is employed for legal purposes in the public, in a court or in the theine justice system; thus, any science that is used for legal purposes is forensic science.

Archimedes' Eureka legend (287–212 B.C.E.) can be considered an early account of the application of forensic science. Archimedes used water displacement principles to argue that a crown was not constructed of gold (as had been believed) based on its density and buoyancy. During the seventh century, fingerprints were used as a technique of establishing identity. Medical evidence was first used to determine the mode of death in China in the 11th century, and it flourished in 16th-century Europe. The Office of the Coroner, which combines a medical and judicial approach to dealing with crimes and is still utilized in the United States today, was founded in England in the 12th century by King Richard I. The coroner system was established by the American colonists, and it is still in use today. There is no requirement that a coroner is a licensed physician under federal law.

The applications of modern forensic science are numerous. In civil situations such as forgeries, fraud, or carelessness, it is used. It can assist law enforcement personnel in determining whether any rules or regulations governing the marketing of foods and beverages, the manufacture of medications, or the use of pesticides on crops have been broken. It can also tell if automotive emissions are below acceptable limits and if drinking water fulfills legal purity standards. Forensic science is used to track whether countries are complying with international accords like the Nuclear Non-Proliferation Treaty and the Chemical Weapons Convention, as well as to determine whether they are building secret nuclear weapons programs. In most crimes involving a victim, such as assault, robbery, kidnapping, rape, or murder, forensic science is applied.

In a criminal inquiry involving victims, the medical examiner is a key character. The medical examiner's job is to go to the crime scene, perform an autopsy (body examination) in cases of death, examine the medical evidence and laboratory reports, research the victim's medical history, and compile all of this information into a report for the district attorney, who is the public prosecuting officer for a specific district. Medical examiners are typically forensic pathologists who specialize in the study of structural and functional changes in the body as a result of injury. Forensic scientists, who are experts in these subjects, may be called upon by the medical examiner to assist in the investigation of a crime. In criminal cases, forensic scientists are frequently involved in the search for an investigation of physical traces that may be beneficial in establishing or disproving a relationship between a suspect and the crime scene or victim. Blood, other bodily fluids, hair, textile fibers from clothing, paint, glass, other building materials, footwear, tool, tire marks, and incendiary substances used to ignite fires are all examples of such traces. Occasionally, the scientist will come to the scene to offer advice on the likely sequence of events and to assist in the early evidence search. Toxicologists are forensic scientists who look for drugs, poisons, alcohol, and other chemicals in a person's bodily fluids, tissue, and organs. Others specialize in weaponry, explosives, or documents of dubious validity.

Dusting the crime scene for fingerprints is one of the earliest forensic science practices. Fingerprinting is a reliable method of identification because no two fingerprints are alike. Law enforcement officials can now digitally record fingerprints and electronically transmit and receive fingerprint information for faster identification thanks to advances in computer technology. DNA fingerprinting is a powerful tool for analyzing blood, hair, skin, and sperm evidence at a crime scene. A laboratory can quickly clone, or replicate, the DNA from a little sample of any of these chemicals using an advanced technology procedure known as the polymerase chain reaction (PCR). This procedure generates enough DNA to compare to a criminal suspect's DNA sample.

Today, forensic science is a high-tech field that analyses and researches evidence utilizing electron microscopes, lasers, ultraviolet and infrared light, advanced analytical chemical procedures, and computerized databanks. Actual blood tests, such as gas chromatography, can be used to determine blood alcohol levels, for example. This approach involves vaporizing a blood sample at a high temperature and passing the gas through a column that separates the various chemical components contained in the blood. Gas chromatography may identify a variety of substances, including barbiturates, cocaine, amphetamines, and heroin, in addition to alcohol.

When a body is located in a lake, stream, river, or ocean with water in the lungs, the medical examiner must determine whether the drowning occurred in the area where the body was discovered or elsewhere. The presence or absence of diatoms, single-celled algae prevalent in all-natural bodies of water, is examined using a conventional microscope that can magnify things to 1,500 times their true size. Because diatoms are removed from domestic water during treatment, the absence of diatoms suggests that the drowning occurred in a sink or bathtub, not where the body was discovered.

The minute gunpowder particles present on the hand of a person who has recently shot a gun are detected using a scanning electron microscope that magnifies items 100,000 times. These particles can also be studied chemically to determine if they came from a certain type of bullet. The presence of a suspect at a crime scene can often be determined through forensic testing of substances found at the scene. Bite marks left by humans can also be used as evidence. Bite marks may be discovered on a homicide victim's body or in food or other items found at the crime scene, such as chewing gum. Liquid plastic can be used to cover the impressions left by these bites by a forensic scientist. When the cast is hardened, it becomes an exceptionally accurate reproduction of the assailant's teeth, which may be compared to a cast made from the suspect's teeth.

FOOD SERVICES

 

FOOD SERVICES

DEFINITION:

Food science is a branch of science that studies all technical elements of food, from harvesting to slaughtering to cooking and consumption. It combines and utilizes knowledge from chemistry, engineering, biology, and nutrition to preserve, process, package, and distribute nutritious, wholesome, inexpensive, desirable, and safe foods.

EXPLANATION:

Food science has evolved over time as new technologies for preserving foods and ensuring public safety have become available. The food system was very different hundreds of years ago than it is now. People in rural areas purchased vast quantities of bulk essentials such as wheat, cereals, and sugar for home preparation, supplementing their staples with whatever fruits and vegetables they could cultivate or gather. These products were purchased in farmers' markets by city dwellers, a habit that is still practiced in many areas today. When preserved in cool, dark rooms called root cellars, some goods, such as potatoes, might last for months. People bought enormous blocks of ice cut from the surfaces of frozen lakes and rivers and preserved perishable meals in their ice boxes before modern refrigerators became accessible.

Throughout history, a variety of ways for preserving foods have been created, including salting meat, drying fruits and vegetables in the sun or over low fires, and turning milk into cheese. Nicholas Appert, a Frenchman, invented a method for preserving food in glass jars in the early 1800s. Appert is known as the "Father of Canning," but he is also hailed as the "Father of Food Science" by some. Modern food science, on the other hand, entails a lot more than only food preservation. Food scientists assist in the development of novel products, the design of manufacturing methods for these foods, the selection of packaging materials, the study of product shelf life, sensory evaluations, and microbiological and chemical testing. Food scientists research more fundamental phenomena that are closely related to the manufacturing of a certain food product and its qualities at universities.

Food science is an applied science that, like engineering, draws on information from a variety of natural science domains to solve practical challenges. Microbiologists, chemists, and physicists are all well-versed in the fundamentals of food science. Food scientists seek to ensure that products are free of bacteria and dangerous substances because food safety is everyone's top priority. The chemical makeup of meals is particularly essential in determining flavor, color, appearance, and texture quality. Food scientists must also have a basic understanding of engineering principles in order to comprehend how a processing method affects the food.

The food industry is relatively immune to the economic ups and downs that other businesses face since people constantly need to eat. Food processing is the largest manufacturing industry in the United States, employing over 14 million people and accounting for 20% of GDP. After graduation, the vast majority of food science majors find well-paying professions.

ECOLOGY

 

ECOLOGY

 

DEFINITION:

Ecology, often known as ecological science, is a discipline of biology that investigates how plants and animals interact with their physical and biological surroundings.

EXPLANATION:

Light and heat, or solar radiation, moisture, wind, oxygen, carbon dioxide, and nutrients in the soil, water, and the atmosphere are all part of the physical environment. Other varieties of plants and animals, as well as organisms of the same sort, make up the biological environment.

Ecology is a subfield of environmental science that is frequently misunderstood. Environmental science also analyses interactions of purely physical characteristics that do not involve biological systems, even though both are multidisciplinary sciences that focus on the interactions of populations of species. Environmentalism, which focuses on human-caused damage to the natural environment, is sometimes confused with ecology. Similarly, the terms ecologic and ecological are used interchangeably to mean "environmentally friendly. "Studies of animal populations and their surroundings can be traced back to the Greek philosopher Aristotle and his follower Theophrastus, despite ecology being a relatively recent study that only gained prominence in the second part of the twentieth century. As early as the fourth century B.C.E., Theophrastus articulated interrelationships among animals and between creatures and their surroundings. With the publication of Charles Darwin's The Origin of Species in 1850, as well as the work of his contemporary and opponent Alfred Russel Wallace, the field began to bloom.

Wallace identified the interconnectedness of animal and plant species and classified them as bioeconomic, or living communities. Eduard Suess, an Austrian geologist, coined the word "biosphere" in 1875 to describe the various conditions that favor life on Earth. Environmentalists and other conservationists have used ecology and other sciences to bolster their advocacy positions since the 19th century. For political or economic reasons, environmentalist viewpoints are frequently divisive.

As a result, some ecological research has a direct impact on policy and political discourse, which in turn influences ecological research. The National Audubon Society, whose public policy office is in Washington, D.C., works with Congress, the executive branch of the federal government, and the media to promote environmental conservation, and is an example of a powerful environmentalist advocacy organization.

The basic tenet of ecology is that every living entity has an ongoing and continuous relationship with every other component of its environment. Ecology can be described as any condition in which creatures interact with their surroundings. Food chains or food webs connect species within the environment. Energy from the sun is acquired by primary producers (plants) via photosynthesis and moves upward up the food chain to primary consumers (plant-eating animals, or herbivores), secondary and tertiary consumers (meat-eating animals, or carnivores), and finally to waste heat. The matter is integrated into decomposers (such as mushrooms and bacteria), which destroy nutrients and return them to the ecosystem as a result of this process. The concept of an ecosystem can be applied to a pond, a field, or a patch of deadwood of various sizes. A micro-ecosystem is a tiny ecological unit. An ecosystem, for example, can be a stone with all the life beneath it. A forest is a meso-ecosystem, whereas an ecoregion is a macro ecosystem.

An ecological crisis can develop when a species or population's environment changes in a way that threatens the species' survival. A change in the climate (such as increased temperature or decreased rainfall), an exceptional incident (such as an oil spill), increased predatory activity (such as overfishing), or explosive development in the population of the species may all trigger the crisis.

Human actions have had a significant impact on many ecosystems during the last few centuries, diminishing the amount of forest on the planet (deforestation), increasing the amount of land devoted to agriculture, buildings, and highways, and polluting ecosystems.

ECOLOGICAL SUBDISCIPLINES

Physiological Ecology (or Ecophysiology) and Behavioral Ecology are two branches of ecology.

These studies look at how an individual adapts to their surroundings.

Ecology of Populations (or Autecology)

This research focuses on the population dynamics of a particular species or a related group of species (such as animal, plant, or insect ecology).

Ecology of the Community (or Synecology)

The interactions between species within an ecological community are the focus of this study.

Ecology of Ecosystems

This research looks at how energy and matter travel across ecological components.

Ecology of the Landscape

This research looks at processes and relationships across different ecosystems or very vast geographic areas (for example, Arctic or polar ecology, desert ecology, tropical ecology, and marine ecology).

Ecology of Humans

As diverse as the ecosystems and animals you research, an ecologist's job options are as many as the environments and animals you study. Basically, an ecologist is needed in any situation where research on the interaction of species and the environment is required. Oceans, deserts, woods, towns, grasslands, rivers, and every other part of the globe are studied by ecologists. Ecologists are increasingly collaborating with physical scientists, social scientists, policymakers, and computer programmers to better understand how species interact with one another and with their surroundings. Educators, technicians, field scientists, administrators, consultants, and authors are all examples of ecologists.

Cell biology

 

Cell biology

 

DEFINITION:

Cells are the smallest, self-contained units of an organism's structure, consisting of a nucleus surrounded by cytoplasm and encased by a membrane.

EXPLANATION:

 Cell biology studies the physiological qualities, structure, organelles (such as nuclei and mitochondria), relationships, life cycle, division, and death of these basic units of organisms at microscopic and molecular levels. Cell biology encompasses both the vast diversity of single-celled creatures like bacteria and the numerous specialized cells found in multicellular species like animals and plants. Cell biology has typically focused on concerns about how organelles perform and interact, how these cellular processes are regulated, and how different cells within an organism communicate with one another. All biological and medical sciences require a basic understanding of cell composition and function. In the domains of cell and molecular biology, examining the similarities and differences between cell types is particularly essential since the concepts learned from researching one cell type can be applied to other cell types. Genetics, biochemistry, molecular biology, and developmental biology are all strongly related to cell biology research. Cell biology has traditionally focused on questions about how organelles work and interact with one another, how cellular processes are regulated, and how different cells within an organism communicate with one another. All biological and medical sciences rely on an understanding of the composition of cells and how they function. In the fields of cell and molecular biology, studying the similarities and differences between cell types is especially important because the principles learned from studying one cell type can be applied to other cell types. Genetics, biochemistry, molecular biology, and developmental biology are all intertwined in cell biology research. Ribosomes in the cytoplasm make the majority of proteins. Protein biosynthesis or protein translation are terms used to describe this process. During synthesis, some proteins, such as those that will be integrated into membranes (membrane proteins), are transported to the endoplasmic reticulum (ER) and processed further in the Golgi apparatus. Membrane proteins can be released from the cell or moved to the plasma membrane or other subcellular compartments from the Golgi. Proteins pass through these compartments regularly. Proteins that are found in the ER and Golgi interact with other proteins but remain in their separate compartments. Other proteins make their way to the plasma membrane via the ER and Golgi.

Biology of Structure

This is the study of biological macromolecules' architecture and shape, particularly proteins and nucleic acids, and what causes them to have the structures they have.

Botany

 

Botany

Define:

Botany is the scientific study of photosynthesis-producing plants or multicellular organisms.

Explanation:

 Botany is often known as plant science or plant biology as a discipline of biology. Botany is a broad field of science that investigates the structure, growth, reproduction, metabolism, development, diseases, ecology, and evolution of plants. Plants are important to study because they are an essential aspect of life on Earth, providing food, oxygen, fuel, medicine, and fibers that enable other living forms to exist. They absorb carbon dioxide, a waste product produced by most organisms, and greenhouse gas that contributes to global warming, through photosynthesis. Plants, like other forms of life, can be examined on a variety of levels. The first is the molecular level, which is concerned with plant biochemistry, molecular biology, and genetics. The morphology and physiology of plants are studied at the cellular, tissue, and organelle (a discrete structure of a cell with a specialized function) level; while interactions within a species, with other species, and with the environment are studied at the community and population level.

 

Botanists used to study any living thing that wasn't an animal. Fungi, algae, and bacteria are now classified as members of other kingdoms, but they are still studied in introductory botany schools, according to the current categorization scheme. The ancient Greeks were among the first to write scientifically about plants. Empedocles, who lived in the fifth century B.C.E., believed that plants, like animals, had a soul, as well as reason and common sense. Plants, according to Aristotle, were in the same category as animals and inanimate objects. Theophrastus, Aristotle's pupil, published two works about plants that were still in use in the 15th century. Carl Linné, a Swedish physician-turned-botanist, is credited with inventing the systematic naming method (nomenclature), which is still used to provide scientific names to all species, plant and otherwise, today. Plants have always been a convenient organism to study scientifically since they do not present the same ethical concerns as an animal or human research. After crossing pea plants in his garden in the 1850s, Austrian monk Gregor Mendel wrote the first rules of inheritance, a set of core ideas relating to the transmission of hereditary features from parent organisms to their children. Barbara McClintock uncovered "jumping genes" and other information regarding inheritance by examining maize plants nearly a century later.

Positions as an ecologist, taxonomist, environmentalist, forester, and plant explorer are among the occupations open to someone who appreciates the outdoors. Biophysics, developmental botany, genetics, modeling, and systems ecology can appeal to someone with a mathematical background. A chemistry enthusiast could work as a plant physiologist, plant biochemist, or molecular biologist. Microbiology, phycology, and mycology are popular choices for people who are captivated by microscopic organisms. Ornamental horticulture and landscape design on a bigger scale necessitates the aesthetic use of plant shape and color. Plant pathology (diseases) or plant breeding can be of interest to someone concerned about the world's food supply.

BIOPHYSICS

 

BIOPHYSICS

Definition:

Biophysics, often known as biological physics, is an interdisciplinary science that uses physics and chemistry concepts, as well as mathematical and computer modeling approaches, to better understand how biological systems work.

Explanation:

Biophysics is a molecular science that aims to explain biological activity in terms of specific molecule structures and properties. Small fatty acids and sugars (1 nanometer (nm), or the width of three atoms), macromolecules such as proteins (5 to 10 nm), starches (greater than 1,000 nm and longer than the thickness of a human hair), and enormously elongated DNA molecules (more than 1 centimeter long but only 20 nm wide) are among the molecules studied or the scaled equivalent of a 45-mile-long strand of thread). The sole building blocks of living organisms, biomolecules, combine into cells, tissues, and entire organisms by producing intricate individual structures observable under a light microscope.

The origins of biophysics can be traced back to the ancient Greeks and Romans, who proposed theories concerning the physical basis for consciousness and perception. It grew rapidly following World War II, fueled in part by the application of nuclear physics to biological systems, such as the study of radiation impacts on living matter. Physicists were introduced to biologists and biological problems as a result of these studies, and biophysics emerged as a new scientific field. The comprehensive exploration of the structure of molecules in biological systems is an important topic of biophysical research. The model of deoxyribonucleic acid (DNA), the genetic material of life, is the most well-known achievement in this field. Furthermore, Francis Crick, the most recognized biophysicist, was one of three people to receive the Nobel Prize for this achievement. The researchers used data from an X-ray crystallography technique that displays the physical patterns of molecules.

Biophysics is now used to answer a variety of biological questions, such as "How can sense organs identify tiny chemicals in our environment and transform them into electrical impulses that deliver information about the outside world to the brain?" To solve such questions, biophysicists use chemical, physical, and biological analysis techniques. They can also use very precise and sensitive physical devices and procedures to monitor the characteristics of the movement of specific groupings of molecules to examine the relationship between biological function and molecular structure. These devices and procedures can even examine, alter, and quantify the behavior of single molecules.

DISCIPLINES IN CONNECTION:

Biophysics, as an interdisciplinary discipline, is used in many investigations of biomolecule structure and function, as well as cellular activity. Here are several examples:

Biological and chemical chemistry

Biomolecular structure, nucleic acid structure, and structure-activity correlations are all covered.

Biology of Structure

This is about high-resolution protein, nucleic acid, lipid, and carbohydrate structures.

Most biophysicists discover their interest in natural phenomena in high school, enjoy riddles and problem solving, and enjoy developing and making things. More colleges and institutions, such as John Hopkins, Duke, and the University of Chicago, are offering undergraduate and graduate degrees in biophysics. Others include a biophysics emphasis in an advanced degree in chemistry, biology, physics, or another subject. Biophysicists can pursue a wide range of occupations due to their extensive education. You could work primarily in a laboratory, dealing with computers, teach, or become a science writer, depending on your interests and abilities. Many biophysicists go on to become professors or staff members at colleges, universities, medical schools, and dentistry schools, and there will be plenty of opportunities for young faculty members in the next two decades. Biophysicists who work in government, private research organizations, or industry have a strong research focus. As a result of recent advances in molecular biophysics and molecular biology, many new jobs have been established in industry. Biophysicists often work in groups with people from various backgrounds, interests, and abilities who collaborate to solve problems.
