Overview
Cell cycle checkpoints are essential control mechanisms that ensure cells divide correctly and maintain genetic integrity. They occur at critical points in the cell cycle: G1, G2, and M phases. Each checkpoint serves a specific purpose, such as assessing DNA damage, ensuring proper replication, and ...
Key Terms
Example: The cell cycle includes G1, S, G2, and M phases.
Example: The G1 checkpoint checks for DNA damage before replication.
Example: Cyclin D is important for the G1 phase.
Example: CDK2 is activated by cyclin E during the G1 phase.
Example: Mitosis occurs after the G2 phase.
Example: UV radiation can cause DNA damage.
