This course explores the field of epigenetics in a discussion-based format, using both primary and secondary scientific literature. Topics focus on cellular differentiation and pathologies derived from the misregulation of epigenetic systems in the cell, including imprinting during development and mutations involving DNA methylation of CpG islands during cancer progression. This course cannot be taken for credit if the student has already received credit for BIOL 388. Prerequisite: BIOL 223 or BIOL 224 or BIOL 280.
