Change in a gene caused by a change in its chemical composition is called:
A) mutation
B) gene drift
C) gene flow
D) speciation

Question

Quizplus · Accepted Answer

A mutation is a change in the DNA sequence of a gene, which can be caused by changes in its chemical composition. This can result in a variety of effects, including changes in protein function, genetic disorders, or even the development of new traits over time through the process of natural selection. Gene drift, gene flow, and speciation are also important concepts in genetics and evolutionary biology, but are not directly related to changes in the chemical composition of genes.
