Epigenetics is the science of living DNA, charting the chemical pathways that spur DNA into action by turning genes on and off. This rapidly advancing field has overturned traditional ideas about heredity, revealing that both behavior and the environment can affect the way our genes work. This series covers this vital science in 12 in-depth, half-hour lectures, presented by noted British epigeneticist, physician, and science communicator Dr. Charlotte Mykura.
