Study Notes
G2 Checkpoint
- Ensures smooth cell division, producing healthy daughter cells with undamaged DNA.
- Occurs before M phase.
- Checks for DNA integrity and replication.
- If errors/damage detected, cell pauses to repair.
- Cell cycle halted if DNA problems are detected.
- Cell attempts DNA replication completion or repair.
- Irreparable damage triggers apoptosis (programmed cell death).
- Apoptosis prevents damaged DNA from being passed to daughter cells.
- Apoptosis crucial for cancer prevention.
