Answer:

DNA copies itself in the INTERPHASE stage of the cell cycle.

The cell cycle is defined as the sequential events, in which the cell and its genetic material make a copy of itself.

The correct option is:

Option A. Interphase

Cell cycle constitutes of Interphase and M or Mitosis phase.

In interphase, the cell undergoes three phases:

  • G1 phase - The phase involves the intermediate phase in which the cell grows in size, synthesis mRNA, and prepares to enter the S phase.

  • S phase - The synthesis phase involves the replication of DNA. The phase occurs between the G1 and G2 phases.

  • G2 phase - The third phase of the cell cycle marks the duplication of the chromosome, and further proteins are required for cell division in the M phase.

Therefore, the correct option is Interphase.
