The course covers the mechanisms by which eukaryotic cells control their duplication in a properly regulated manner. A large emphasis will be placed on the controls that cells employ to replicate and segregate their chromosomes with the necessary precision. In addition, the course will examine the mechanisms by which cells detect and rectify damaged DNA throughout the cell cycle. These various processes, collectively known as checkpoint-regulatory mechanisms, lie at the heart of how organisms maintain genomic integrity throughout their lifetimes. These pathways are essential for the prevention of cancer, birth defects, and other maladies. As part of the course, students will give presentations on key publications in the field, including both classic papers and newer papers that employ cutting-edge technologies.
