Describe anaphase in mitosis.
Advertisements
उत्तर
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.
