Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
Using three examples, describe how allosteric sites are important in the function of genetic regulatory proteins.
Enzymes are proteinaceous catalysts that are genetically encoded by the cell often present with non-protein cofactors. Enzymes and substrates bind by the "induced fit" technique, followed by slight conformational modifications upon substrate contact, causing binding to the active site of the protein. This change in the shape of the enzyme allows rapid binding of potential substrates incorrect orientation ion the active site
Allostery is described as the process of modulating the activity of a protein at a site other than the active site called an allosteric center. The particular expression of a gene is achieved through the interaction and binding of protein transcription factors to unique DNA sequence domains found in the regulatory region of the gene usually distinct from the coding region.
