What happens to the chromosomal material during prophase?
Options
- AIt becomes tangled
- BIt remains unchanged
- CIt becomes untangled
- DIt is destroyed
Correct answer
C. It becomes untangled
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. he centrosome, which had undergone duplication during S phase of interphase, now begins to move towards opposite poles of the cell. The completion of prophase can
