There are many points during the cell cycle when the process of division may stop because of a problem. Sometimes the process doesnβt stop. Summarize the function of apoptosis in the cell cycle.
to repair damaged or old cells
to destroy damaged or old cells
to allow the cell to rest before the cell cycle restarts
to facilitate cell reproduction before the cell cycle restarts
When mutated cells ignore checkpoints, they reproduce uncontrollably, forming tumors. During which stage of the cell cycle does the cell divide into two cells?
M
G1
S
G2

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)
G1 Checkpoint
G2 Checkpoint
M Checkpoint
No checkpoint meets these criteria.
