What happens to the centrosome during prophase?
What happens to the centrosome during prophase?
Options
- AIt remains unchanged
- BIt begins to move towards opposite poles of the cell
- CIt is destroyed
- DIt becomes tangled
Correct answer
B. It begins to move towards opposite poles of the cell
Step-by-step solution
Chromosomal material condenses to form compact mitotic chromosomes. Chromosomes are seen to be composed of two chromatids attached together at the centromere. The centrosome, which had undergone duplication during S phase of interphase, now begins to move towards opposite poles of the cell. Each centrosome radiates out microtubules called asters. The two asters together with spindle fibres forms mitotic apparatus.
