Biology · CELL CYCLE AND CELL DIVISION

During anaphase of mitosis, how do the splitting chromosomes orient themselves while moving toward opposite poles?

1. A
   Centromeres remain clustered at the spindle equator while arms touch the poles
2. B
   Arms of the chromosomes lead towards the pole while the centromere trails behind
3. C
   Centromere is directed towards the pole at the leading edge while the arms trail behind
4. D
   Sister chromatids rotate perpendicular to the spindle axis without poleward movement
