This is Us 2: DNA is Not the Whole Story - How Epigenetics Controls Our DNADNA refers to the ~3.2 billion ACGT letters that make up our chromosomes. If we look at DNA as the hardware of physiologic control and heredity, what is the software that controls the DNA hardware? Epigenetics refers to all the processes that regulate how our DNA is expressed (or not expressed as the case may be). While we cannot control our DNA letter sequence, we can influence the epigenetic software that controls it. We will learn about the structure and function of DNA, how epigenetics packages and decorates DNA, and what we can do to influence our personal epigenetic landscape for optimal health and aging.
