Answer:
The correct answer is - at the G1/S phase and G2/M phase.
Explanation:
The G1/S transition phase or checkpoint is a phase where the cell cycle arrested if during the evaluation of the DNA found damaged or other factors including external factors. Due to this evaluation and inadequate conditions, the cell will not enter the S phase.
The G2/M phase or transition phase is a checkpoint which takes place just before the M phase that ensures that all replicated DNA is not damaged before entering mitosis phase or M phase.
Thus, the correct answer is - at the G1/S phase and G2/M phase.
