cell cycle regulation

Cell cycle regulation is the process that ensures cells grow and divide at the right time. The cell cycle has several phases: growth, DNA replication, and division. Regulatory proteins called cyclins and cyclin-dependent kinases (CDKs) control these phases by acting as checkpoints to prevent errors. If a cell encounters damage or issues during these checkpoints, it can either repair itself or stop dividing altogether. Proper regulation is crucial for healthy growth, and when it goes awry, it can lead to problems like cancer, where cells divide uncontrollably.
