What Role Do Genes Play In The Sequence Of DNA Molecules
Genes are the smallest functioning unit in the genetic system, which play a vital role in the control and function of the body. A gene is simply a sequence of DNA bases, which can be composed from four types of nucleotide base either adenine, thymine, cytosine or guanine. The order and combination of these bases in the sequence determines the type of amino acid produced, which influences the polypeptide produced at the end of protein synthesis.
