What is epigenetics?

Posted March 18, 2024


Answer

Epigenetics explores how cells regulate gene expression without altering the underlying DNA sequence. Epigenetic changes refer to alterations to DNA that influence whether genes are activated or silenced. Epigenetic changes, unlike genetic alterations, are reversible modifications. However, they can alter how the body reads DNA sequences.
