How do genes regulate the cell cycle

WebSep 4, 2024 · The cell cycle is controlled by a number of protein-controlled feedback processes. Two types of proteins involved in the control of the cell cycle are kinases and cyclins. Cyclins activate kinases by binding to them, specifically they activate cyclin-dependent kinases (CDK). WebApr 12, 2024 · The circadian clock is a crucial biological mechanism that enables organisms to anticipate the daily light/dark cycle. While the circadian clock factors underlying the molecular mechanism were characterized in a few model organisms, the evolutionary functional origin of the core clock proteins is unclear.
