A cell contains DNA damage that causes it to undergo apoptosis before reaching mitosis. This cell had twice the amount of DNA for a cell of this type. During which checkpoint did this cell trigger apoptosis?(1 point)

Question

Responses

G1
Checkpoint
cap g sub 1 Checkpoint

G2
Checkpoint
cap g sub 2 Checkpoint

M
Checkpoint
cap m Checkpoint

No checkpoint meets these criteria.

Answer 1

The cell described has twice the amount of DNA, indicating that it has likely completed DNA replication. The presence of DNA damage that prompts apoptosis suggests that the cell has mechanisms in place to prevent damaged cells from progressing to mitosis. In the context of the cell cycle, this scenario most closely aligns with the G2 checkpoint.

During the G2 checkpoint, the cell checks for DNA damage and ensures that all DNA has been accurately replicated before entering mitosis. If there is damage or other issues detected, the cell can trigger apoptosis to prevent the propagation of potentially harmful mutations.

Therefore, the correct response is:

G2 Checkpoint
