/hich of the following statements about mitosis is incorrect? A. The daughter nuclei are genetically identical to the parent nucleus B. Chromosomes separate during anaphase due to the interaction of polar microtubules from opposite poles pushing against each other C. Chromosomes separate during anaphase when the kinetochore microtubules shorten as they depolymerize D. Chromosomes move to the metaphase plate using motor proteins, a kind of kinesin, attached to spindle fibers
