A gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis. gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA).

A: Deoxyribonucleic acid (DNA) carries the sequence of coded instructions for the synthesis of proteins, which are transcribed into ribonucleic acid (RNA) to be further translated into actual proteins. The process of protein production involves two steps: transcription and translation.
