Answer 1

The cell described in your scenario has twice the amount of DNA and undergoes apoptosis before reaching mitosis. This indicates that the cell likely encountered problems during the G2 phase of the cell cycle, which is responsible for DNA repair and the preparation for mitosis.

In the G2 checkpoint, the cell checks for DNA damage and ensures that all DNA has been replicated properly before proceeding to mitosis. If there is significant DNA damage, the cell can trigger apoptosis to prevent the propagation of damaged DNA.

Therefore, the correct response is:

G2 Checkpoint
