Epigenetics | The Longevity Revolution | Mobile

Paul Andersen explains the concepts of genetics. He starts with a brief discussion of the nature vs. nurture debate and shows how epigenetics blurs this distinction. He explains how differentiation of cell types results from the inactivation of certain genes. He describes the three processes of epigenetics: DNA methylation, Histone acteylation and microRNA.
