Cyclin-CDK complex

The Cyclin-CDK complex is a key regulator of the cell cycle, which is the process that cells go through to divide and replicate. Cyclins are proteins that help control the cycle's timing, while Cyclin-dependent kinases (CDKs) are enzymes that, when activated by cyclins, trigger specific events in the cell cycle. Together, they work like a switch that signals the cell to move from one phase to another, ensuring that cell division occurs accurately and at the right moment. This regulation is crucial for growth, development, and maintaining healthy cells.
