हिन्दी

During anaphase of mitosis, as daughter chromosomes migrate toward opposite poles, the orientation of their structural regions is such that:

Both chromatid arms lead toward the pole while the centromere trails behind
Kinetochores dissociate completely allowing arms to lead
Chromatids move parallel to the equatorial plate with no fixed polarity
The centromere of each chromosome is directed towards the pole at the leading edge, with the arms trailing behind

Correct answer · Option 4

The centromere of each chromosome is directed towards the pole at the leading edge, with the arms trailing behind

Explanation

During anaphase, the centromere remains directed towards the pole and hence at the leading edge, with the arms of the chromosome trailing behind.
