Unformatted text preview: BIO315H Cell cycle regulation November 8, 2006 The cell cycle is an excellent topic for understanding the way which a cell can regulate its ongoing activities. For example, cell division is governed in part by extracellular signals that are detected by plasma membrane receptors and converted into intracellular information through signal transduction (Monday’s topic). In addition to this extrinsic information, the cell also relies on intrinsic information about the status of its chromosomes before proceeding with the ‘decision’ to divide, including both signaling pathways and internal gene expression. Finally, the master regulators of progression through the cell cycle are enzymes which both function as kinases and also are themselves the targets of other kinases. The primary goal of today’s lecture is to understand the key molecular events that control the progress of a mitotic cell as it transitions through the...
