Mitosis occurs in a series of tightly regulated stages. Disruption of any of these stages can hinder chromosomal transmission during mitosis. Suppose that vinblastine, a chemotherapeutic medication that specifically targets and disrupts microtubules, is applied to a cell culture undergoing mitosis. Which of the following best explains how this medication will affect the transmission of chromosomes to daughter cells?

A) The daughter cells will remain genetically identical to their parents because microtubules are only involved in degradation of the nucleus during prophase.
B) The daughter cells will not be genetically identical. Microtubules are involved only in alignment of chromosomes at the midline during metaphase and separation during anaphase.
C) The daughter cells will not be genetically identical because microtubules are only required for a process in which homologous chromosomes exchange genetic information during prometaphase.
D) The daughter cells will not be genetically identical because microtubules are involved in the formation of the spindle apparatus during prophase, attachment to the kinetochore during prometaphase, alignment of chromosomes at the midline during metaphase, and separation during anaphase.
