Cell Division Checkpoints: Ensuring Proper Cell Division Process

What are the checkpoints that determine if cell division has occurred properly?

Which of the following checkpoints determines if cell division has occurred properly?

A. M checkpoint

B. G1 checkpoint

C. G2 checkpoint

Answer:

G1 checkpoint

Cell division has two checkpoints, namely the G1 checkpoint and the spindle assembly checkpoint. The checkpoint that determines if division has properly occurred is the G1 checkpoint. At this point, if damage in the DNA is detected or if the cell has not reached the optimum size, the cell is stopped in G1 and is not allowed to proceed to further processes.
