Epigenomics

Epigenomics is the study of changes in gene activity that do not involve alterations to the DNA sequence itself. Think of DNA as the blueprint for building an organism, where epigenomics represents the instructions for when and how to use that blueprint. Factors like environment, lifestyle, and experiences can trigger chemical modifications that affect gene expression, turning genes on or off. This can influence traits, development, and even disease risk, highlighting the role of both genetics and external factors in shaping who we are.
