Overview
The regulation of the cell cycle is a complex process that ensures cells divide correctly and at the right time. Key components include checkpoints that monitor the cell's readiness to progress through the cycle and cyclins that activate cyclin-dependent kinases (CDKs) to drive the cycle forward. Un...
Key Terms
Example: The cell cycle includes interphase and mitosis.
Example: The G1 checkpoint checks for DNA damage before replication.
Example: Cyclin D is important for the transition from G1 to S phase.
Example: CDK2 is activated by cyclin E to promote DNA synthesis.
Example: Cells that are damaged beyond repair may undergo apoptosis.
Example: Mitosis is essential for growth and tissue repair.
