While genetics is the study of the DNA code that describes how to make all our cells and tissues, epigenetics is the study of how the body adds and removes chemical tags to our DNA, to turn certain genes on or off. This pattern of chemical tagging is generally passed on from parent cell to daughter cell, along with the DNA. Researchers at The Ottawa Hospital are leading the way in studying epigenetics and using it to develop new therapies. Learn more from the Ottawa Centre for Epigenetics Research.
