Question

True or False: If a cell moves pass the M phase checkpoint this means that the DNA chromosomes are not correctly aligned in the middle of the cell or attached to the spindle fibers. 
-true
-false​

Answer 1

Answer:

False

Explanation:

Cell cycle checkpoints are points in the cell cycle when the cell can halt the cell cycle in response to errors or when conditions are not optimal for dividing.

The M checkpoint ensures that mitotic spindle is attached to the chromosomes and that they are aligned properly in the middle of the cell.

If the cell halts at the checkpoint, then the chromosomes are not aligned properly and the spindle is not attached.

If the cell passes through the checkpoint, the chromosomes are properly aligned and the spindle is attached ready to proceed with mitosis.
