Question

Which statement best describes chromosomal movement during mitosis?

Select one:
a. Microtubules bind tubulin polymers on centromeres to initiate homologous chromosome separation.
b. Each centrosome binds an individual chromatid to ensure equal division.
c. Centrioles on chromatids bind kinetochores to rays sent by the asters.
d. Each centrosome binds an individual chromatid to ensure unequal division.
e. Centrioles send out microtubules, which bind to kinetochores to pull chromatids apart.

Answer 1

e. Centrioles send out microtubules, which bind to kinetochores to pull chromatids apart.

Step-by-step explanation:

The centrioles are structures formed by microtubules that move to opposite poles during cell division, while the microtubules are polymers of tubulin that conform to the cytoskeleton, which provides the structure to the cell and is associated to its division during mitosis and meiosis. The kinetochore is assembled in the centromere region where binds the chromosomes to the mitotic spindle microtubules. These filaments (microtubules) bind to the kinetochore of sister chromatids in order to separate them during anaphase.
