Which of the following is correct about phases of the cell cycle?

Options

  1. AIn G 1 -phase, DNA content is double the amount of DNA present in the original cell.
  2. BDNA replication takes place in S-phase.
  3. CA short interphase is followed by a long mitotic phase.
  4. DG 2 -phase follows mitotic phase.

Correct answer

B. DNA replication takes place in S-phase.

Step-by-step solution

S Phase or Synthesis phase- It is synthetic phase. It occurs between G 1 phase and G 2 phase. Replication of DNA takes place during this S Phase and the DNA content doubles.
