Question

Quizplus · Accepted Answer

Epigenetics is the study of changes in gene expression that do not involve alterations to the DNA sequence itself. It involves modifications to the DNA molecule, such as the addition or removal of chemical groups, which can turn genes on or off. These modifications can be influenced by environmental factors, such as diet or exposure to toxins, and can be passed on to future generations.
