Question

Describe anaphase in mitosis.

Short/Brief Note
Advertisements

Solution

In anaphase, the two chromatids separate at the centromere and begin to move in opposite direction towards either end of the spindle network called the poles. The chromosomes bend around the centromere showing a 'V' or 'J' or 'L' shaped structure based on the length of its arms.
