During the Metaphase Checkpoint, What Information is Being Checked by the Cell

Question

During the metaphase checkpoint, what information is being checked by the cell?
A) if it is large enough to divide
B) if its DNA has been replicated correctly
C) if its chromosomes are properly attached to microtubules
D) if there are sufficient nutrients available

Accepted Answer

The metaphase checkpoint is responsible for checking if all the chromosomes are properly attached to the spindle fibers or microtubules. If this attachment is not proper, then the cell will not proceed to the next phase, which is anaphase. This ensures that there are no errors in chromosome distribution during cell division.
