Biology

The correct answer is: D.It stops and attempts repair or is arrested until the damage is fixed.

If DNA damage is detected during the G2 phase, the cell typically activates DNA repair mechanisms. The G2 checkpoint will halt the cell cycle, preventing it from entering mitosis until the damage is repaired. If the damage is irreparable, the cell may undergo apoptosis (programmed cell death).

Explanation of other options:

A.It immediately enters mitosis: If DNA damage is detected, the cell does not proceed directly into mitosis. The checkpoint mechanism halts progression until the damage is fixed.
