Each amino acid could potentially exist as one of two possible enantiomers, known as the D-form and the L-form (based on the arrangement of thegroups attached to the asymmetric α carbon). However, in all organisms, only L-amino acids are found in proteins. What does this suggest about the evolution of proteins?
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.
