Which is the first stage of mitosis follows the S and G2 phases of interphase?

Which is the first stage of mitosis follows the S and G2 phases of interphase? Correct Answer Prophase

The correct answer is Prophase.

Key Points

  • Prophase which is the first stage 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 centriole, which had undergone duplication during the S phase of interphase, now begins to move towards opposite poles of the cell.
  • Chromosomal material condenses to form compact mitotic chromosomes.
  • Chromosomes are seen to be composed of two chromatids attached together at the centromere.
