Epigenomics
Pronunciation
The study of all of the epigenetic changes in a cell. Epigenetic changes are changes in the way genes are switched on and off without changing the actual DNA sequence. They may be caused by age and exposure to environmental factors, such as diet, exercise, drugs, and chemicals. Epigenetic changes can affect a person’s risk of disease and may be passed from parents to their children. (NCI Dictionary)
