Explore epigenetic mechanisms that involve covalent modifications of the three major biomolecules: DNA, RNA, or proteins in the context of gene expression and genome stability. Examine how environmental and intrinsic factors regulate these mechanisms to impact normal and diseased cell functions, particularly as they relate to human health, aging, and behavior. Only one of the following may be counted: Biology 327E, 337 (Topic: Epigenetics), 356E, Molecular Biosciences 356E. Three lecture hours a week for one semester.
