When a gene is duplicated one or more times,it gives rise to a group of genes that may diverge by mutation,but their sequences will generally remain closely related and they will encode similar polypeptides.The proteins and genes produced in this way can be referred to as ________.

Question

Quizplus · Accepted Answer

When a gene is duplicated, it can form a group of related genes called gene families. These genes may diverge by mutation but still encode similar proteins or polypeptides. Therefore, option D (gene families) is the best choice for this question. Option A (isotopes) refers to atoms with the same number of protons but different numbers of neutrons, while option B (isomers) refers to molecules with the same chemical formula but different structures. Option C (isosceles) is a geometry term that refers to a triangle with two equal sides. Option E (gene isoforms) refers to different variations of the same gene resulting from alternative splicing or post-translational modifications.
