Quizplus · Accepted Answer

A gene is defined as a segment of DNA that carries instructions for one polypeptide chain, meaning it contains the information necessary to produce a protein. While RNA messengers are involved in the process of protein synthesis, they are not the same as a gene. Noncoding segments of DNA are not considered genes because they do not provide the necessary information for protein production. Triplets of nucleotides in DNA, known as codons, do specify amino acids, but they are not the same as a gene.
