Cell Cycle Regulators: Description & Proteins StudySmarter

WebThe cell cycle is a ubiquitous and complex process that takes place in a cell leading to the production of two daughter cells. Precise regulation of this process is necessary to ensure the genetic integrity of a cell. Cyclins and cyclin-dependent kinases are central to this cycle. WebThese cell cycle regulators are cyclins and cyclin-dependent kinases (Cdk). Cyclins are cell cycle regulatory proteins that "switches" kinases on and off. Cyclins can be categorized … WebEach step of the cell cycle is monitored by internal controls called checkpoints.
