Chromosomes separate during anaphase when the kinetochore microtubules shorten as they depolymerize

Chromosomes move to the metaphase plate using motor proteins, a kind of kinesin, attached to spindle fibers

The daughter nuclei are genetically identical to the parent nucleus

Chromosomes separate during anaphase due to the interaction of polar microtubules from opposite poles pushing against each other
