Q. Assertion :During anaphase, centromere of each chromosome splits and chromatids separate.
Reason ::During anaphase, chromatids move to opposite poles.

Cell Cycle and Cell Division

Solution:

In anaphase, chromosomes are arranged on the equatorial plate for a short period. In anaphase centromeres of chromosomes start to divide into two, forming daughter chromatids with centromere in each. Daughter chromosomes are repulsive so, migrate towards opposite poles. Spindle fibres attached to the centromeres shorten and pull the chromosomes to the poles. In anaphasic movement of chromosomes, the centromeres lead the path while the limbs trail behind. So anaphasic chromosomes appear as $V-, L-, J-$ and $I$-shaped.
