Answer:

G1 Checkpoint

Step-by-step explanation:

Data indicates that the G1 checkpoint is activated in response to mitotic DNA damage in the presence of p53, and that the mitotic DNA damage response is connected to the G1 checkpoint by p53. If cells continue to possess damaged DNA, apoptosis is induced in a p53-dependent manner.
