During metaphase of mitosis, chromosomes:
Undergo coiling
Move towards the pole
Line up at the equator
Break and disintegrate
In Anaphase of mitosis: (I) Chromosomes move to equator and get aligned along metaphase plate. (II) Centromere of each chromosome is towards the equator when chromosomes move away from the equatorial plate. (III) Each chromosome arranged at the metaphase plate splits simultaneously.
(a) Chromosomes move to spindle equator and get aligned along metaphase plate.
(b) Centromere of each chromosome is towards the equator when chromosomes move away from the equatorial plate.
