'''Epigenetics''' refers to changes to a [[gene]]'s activity, expression, and/or regulation that do not involve changes to the [[DNA]] sequence.  This concept is important because it implies that lifestyle of environmental factors influence whether certain genes with harmful potential express or not.  Thus, possessing a gene associated with a disease does not always mean that a person will show symptoms of that disease.
'''Epigenetics''' is the study of how a person's behavior and environment can cause changes that affect the way their genes work. Unlike genetic changes, epigenetic changes are reversible and do not change a person's DNA sequence, but they can change how a person's body responds to, or does not respond to, a DNA sequence.<ref name=CDC /> The discovery that lifestyle choices and/or environment can affect whether certain genes "express" is of great importance in the field of health care, suggesting benefits for preventive education.


It is possible for epigenetic changes to pass from one [[generation]] to the next.

Epigenetics is the study of how a person's behavior and environment can cause changes that affect the way their genes work. Unlike genetic changes, epigenetic changes are reversible and do not change a person's DNA sequence, but they can change how a person's body responds to, or does not respond to, a DNA sequence.[1] The discovery that lifestyle choices and/or environment can affect whether certain genes "express" is of great importance in the field of health care, suggesting benefits for preventive education.
