Question

Quizplus · Accepted Answer

Epigenetics is the study of changes in gene expression that are not caused by alterations in the DNA sequence itself. Instead, epigenetic changes occur due to modifications to the DNA molecule or the proteins associated with it that affect whether or not particular genes are expressed. Thus, epigenetics is most concerned with how external inputs, such as environmental factors, influence gene expression.
