What is happening during the checkpoint in the M-phase of the cell cycle?

a)

The cell is checking to see whether or not to proceed with division based on factors such as cell size, nutrients or growth factors.

b)

All checkpoints are the same, it is just a routine check to cell if the cell is healthy and functioning properly.

c)

The cell is checking to make sure that all spindle fibers are attached to the centromere of all chromosomes, to ensure that each new cell gets a complete set of chromosomes.
