Question

the centrioles, in centrosomes, move to opposite poles during ______ .
a telophase
b prophase
c metaphase
d anaphase

Explanation:

To solve this, we recall the stages of cell division (mitosis). In prophase, the centrioles (within centrosomes) migrate to opposite poles of the cell to form the spindle apparatus. Telophase is about nuclear envelope reformation, metaphase is chromosome alignment at the equator, and anaphase is sister chromatid separation. So the centrioles move to opposite poles in prophase.

Answer:

B. prophase
