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?

Question

G1 checkpoint
G2 checkpoint
M checkpoint
No checkpoint meets these criteria

Answer 1

The correct answer is the G2 checkpoint. The G2 checkpoint ensures that the cell has replicated its DNA correctly before entering mitosis. If a cell has excessive DNA damage, it will trigger apoptosis during the G2 checkpoint to prevent the transmission of damaged DNA to daughter cells.
