Cell division,which is the climax of the cell cycle,consists of
A) chromosome replication and separation.
B) the breakup of the nucleus at the metaphase plate.
C) cytokinesis plus mitosis or meiosis.
D) the formation of a new karyotype.

Question

Quizplus · Accepted Answer

Cell division consists of cytokinesis, the division of the cytoplasm, and either mitosis or meiosis, the division of the nucleus. During cytokinesis, the cytoplasmic contents are divided between the two daughter cells. During mitosis or meiosis, the replicated chromosomes are separated and distributed to the daughter cells. Chromosome replication occurs earlier in the cell cycle, during the S phase. The breakup of the nucleus at the metaphase plate is a step within mitosis, not cell division as a whole. The formation of a new karyotype refers to changes in the number or structure of chromosomes, which can occur due to errors during cell division but is not a characteristic or goal of cell division itself.
