Which of the following constitutes a gene?
A) A pair of nucleotides

Question

Quizplus · Accepted Answer

A gene is a segment of DNA that contains instructions for the production of a functional molecule, either RNA or protein. Therefore, a length of DNA constitutes a gene. A pair of nucleotides is too short and cannot code for a functional molecule on its own. A sequence of amino acids is a product of a gene, but not the gene itself. A set of proteins is also a product of a gene, but not the gene itself.
