What is the formation of mitotic apparatus during prophase?
Options
- AThe formation of two asters and spindle fibres
- BThe formation of three asters and spindle fibres
- CThe formation of four asters and spindle fibres
- DThe formation of two asters and spindle fibres (Correct)
Correct answer
D. The formation of two asters and spindle fibres (Correct)
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. Centrosome which had undergone duplication during interphase, 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.
