What happens to the centrosome during prophase?
Options
- AIt remains at the same location
- BIt begins to move towards opposite poles of the cell
- CIt begins to move towards the same pole of the cell
- DIt does not move
Correct answer
B. It begins to move towards opposite poles of the cell
Step-by-step solution
Prophase which is the first stage of karyokinesis of mitosis follows the S and G2 phases of interphase. In the S and G2 phases the new DNA molecules formed are not distinct but intertwined. Prophase is marked by the initiation of condensation of chromosomal material. The chromosomal material becomes untangled during the process of chromatin condensation. The centrosome, which had undergone duplication during S phase of interphase, now begins to move towards opposite poles of the cell.
