What happens to the centromere of each chromosome during anaphase?
Options
- AIt splits and separates
- BIt moves to the equatorial plate
- CIt remains directed towards the pole
- DIt attaches to spindle fibres
Correct answer
C. It remains directed towards the pole
Step-by-step solution
At the onset of anaphase, each chromosome arranged at the metaphase plate is split simultaneously and the two daughter chromatids, now referred to as daughter chromosomes of the future daughter nuclei, begin their migration towards the two opposite poles.As each chromosome moves away from the equatorial plate, the centromere of each chromosome remains directed towards the pole and hence at the leading edge, with the arms of the chromosome trailing behind. Thus, anaphase stage is characterised by the following key e
