Anettt [7]

Epigenetics is the study of how the structure and function of genes interact with our environment to influence behavior.

In addition to your surroundings and habits, such as what you eat and how much exercise you get, your genes play a significant part in determining your health. The field of epigenetics investigates how environmental factors and behavior may alter how your genes function. Gene-environment interactions that result in the expression of different phenotypes throughout development are the basis for the initial usage of the term "epigenetics." To turn on or off the genes that cause long-lasting alterations linked to the differentiation of various cell types, epigenetic processes are frequently used.

Epigenetics is the study of how DNA sequences are maintained as genes are controlled by cells. DNA alterations known as epigenetic changes control whether or not genes are activated.
