Which of the following statements is FALSE?
A.
Centrosomes are anchor points for microtubules and are essential to form the mitotic spindle.
B.
In the eukaryotic cell cycle the cell spends much more time in the interphase than in the mitotic phase.
C.
In telophase two nuclear envelopes are fully formed and the cell splits in two via cytokinesis.
D.
The contraction of the kinetochore microtubules leads to the separation of the sister chromatids during anaphase.

A. The chromosomes align midway between spindle poles.
B. The sister chromatids separate and move toward the spindle poles.
C. Spindle microtubules attach to each sister chromatid as the nuclear envelope breaks up.
D. A nuclear envelope forms around each set of chromosomes to form four haploid nuclei.
