What is a Phenotype? Examples of Phenotypes and Mendel’s Peas

What is a Phenotype? A Phenotype is the physical expression of DNA. Rather, a genotype is the chemical composition of DNA that causes a particular phenotype. DNA is first transferred to RNA, which is a separate information molecule, which can then be translated into protein. Phenotypes are caused by interactions of many different proteins produced by DNA. … Read more

Gene Definition, Overview, Examples, And Genetic Terms

Gene Definition A gene is a highly specific sequence of nucleotide monomers that can fully or partially regulate the expression of one or more traits in every type of living organism. Genes are formed from deoxyribonucleic acid (DNA) and in the case of some viruses, ribonucleic acid (RNA) polymers. Overview|Gene Definition It was Wilhelm Johansen … Read more

Abiogenesis Definition, Overview, Theory of Abiogenesis

Abiogenesis Definition Abiogenesis is the formation of organic molecules by forces other than organisms. While organisms can form carbon-carbon bonds relatively easily to enzymes, doing so would otherwise require large inputs of energy. Early in the history of science, this fact was used to dispute evolutionism, as it could not be imagined how organic molecules … Read more

What is an antibody? Function, Structure, Autoimmune disease

What is an antibody? Antibodies, also known as immunoglobulins, are glycoproteins produced naturally in response to invasive foreign particles (antigens) like microorganisms and viruses. As such, they play a critical role in defending the immune system against infection and disease. Antigens recognized and bound by antibodies can be proteins such as receptors expressed on cancer … Read more

Genetic Definition, History, And Impact

Genetic Definition Genetics is the study of genes and inheritance in living organisms. This branch of science has a fascinating history, stretching from the 19th century when scientists began to study how organisms inherited the traits of their parents, until today when we can read the “source code” of the living beings letter by letter. … Read more

Definition Bioremediation, Principle, Categories, Methods and Applications

Definition Bioremediation, Principle, Categories, Types and Applications Bioremediation refers to the use of natural microorganisms or deliberately introduced to consume and decompose environmental pollutants, to clean up a polluted site. It is a process that primarily uses microorganisms but also plants or microbial or plant enzymes to detoxify contaminants in soil and other environments. The … Read more

Enzymes Definition, Properties and Mechanism

Enzymes Definition Enzymes are biological macromolecules that accelerate the speed of biochemical reactions without undergoing any changes. They are also called biological catalysts. An enzyme is a highly selective catalyst that greatly accelerates both the speed and the specificity of metabolic reactions. What are Enzymes? Enzymes help speed up chemical reactions in the human body. They bind to … Read more
