In cell cycle the following happens DNA damage is repaired a

In cell cycle the following happens:

DNA damage is repaired at M phase.

DNA damage is checked at the Anaphase.

DNA misalignment stops cell cycle.

All above.

None above

Solution

Correct answer is : DNA misalignment stops cell cycle

Explanation: DNA damage is not repaired at M phase,it is checked. DNA damage is not checked at the Anaphase as there is no such check point. In metaphase checkpoint misalignment of chromosome causes delayed anaphase. Means cell cycle is stopped there until the chromosomes are aligned and appropriately attached. Chromosomes consist of DNA.
