    Question

    In mitosis, the copy of chromosomes appears during

    1. Early prophase
    2. Late prophase
    3. Interphase
    4. Late telophase

    Hint:

    The phase is also called as "S" phase.

    The correct answer is: Interphase

      • S phase or interphase is the initial phase marking the starting of a cell division
      • The genetic material or the DNA replicates before a cell divides
      • 46 pairs of chromosomes are duplicated during S phase
      • S phase is followed by prophase where the condensation of chromosomes occur
