Correct order of the 4 checkpoints of the cell cycle

• Anaphase checkpoint, mitosis/metaphase checkpoint, and telophase checkpoint, interphase checkpoint

• Interphase checkpoint, S phase checkpoint, and M phase checkpoint, mitosis/metaphase checkpoint

• G1 checkpoint, G2 checkpoint, mitosis/metaphase checkpoint, and S phase checkpoint

• G1 checkpoint, S checkpoint, G2 checkpoint, and mitosis/metaphase checkpoint

✓ No DNA damage

✓ Sufficient resources

• G1 checkpoint

• S checkpoint

• G2 checkpoint

• M checkpoint
