If the m checkpoint is not cleared, what stage of mitosis will be blocked?
prophase
prometaphase
metaphase
anaphase

Anaphase

Explanation:

The M check-point of the cell cycle regulates the cell cycle by checking if all the chromosomes are attached properly to the spindle fibers. This checkpoint also ensures that chromosomes are aligned properly at the cell's equator.

If these conditions are met, the M checkpoint allows the cells in the metaphase to progress towards the anaphase. However, any deviation from above-mentioned conditions prevents the cells in the metaphase to enter the anaphase.
