Damaged or improperly replicated DNA would halt progression through the cell cycle at the G2 checkpoint.
There are 3 main checkpoints in the cell cycle:
- G1 checkpoint
- G2 Checkpoint
- M checkpoint
At G1, the size of the cell and the integrity of its genome is checked before the cell irreversibly commits itself to the next stage. Without meeting the necessary requirements, a cell will not move to the S phase of the cell cycle from the G1 phase.
At G2 checkpoint, the cell size, protein level, and proper replication/integrity of the chromosomes are checked before the cell moves to the active division phase. Thus, improperly replicated or damaged DNA will make a cell perpetually stay in G2 until the conditions are fixed.
