How do the A, P, and E ribosomal sites differ functionally during protein synthesis?
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.
How do the A, P, and E ribosomal sites differ functionally during protein synthesis?
Protein synthesis is a cellular process through which cells produce polypeptide chains (proteins) that are essential for the structure as well as the function of cells. It takes place in ribosomes in two stages, namely transcription, and translation.
During transcription, the genetic instructions in DNA are transferred to messenger RNA (mRNA). During translation, the genetic code in mRNA is translated to synthesize proteins. Ribosomes contain three binding sites, namely A site, P site, and E site that help in the accommodation of transfer RNAs (tRNAs).
