Question

Quizplus · Accepted Answer

Epigenetics is the study of the mechanisms that control gene expression and the effects of gene expression on behavior and health. It involves the study of heritable changes in gene function that do not involve changes to the underlying DNA sequence. This includes modifications to DNA and chromatin structure that can affect how genes are turned on or off, as well as the influence of environmental factors on gene expression.
