Question

DNA replicates during:

• A. $G_2$ phase
• B. M phase
• C. S phase
• D. $G_1$ phase

Answer 1

The correct option is C S phase

• The cell cycle has 2 phases the M phase and the Interphase.
• The interphase is made up of G1, S and G2 phase.
• The G1 phase is present after the M phase where the cell divides and in G1 phase the cell is provided time to rest before it can start to prepare for another cell division. Here it performs the normal functions of the cell.
• The S phase takes place after the G1 phase where the DNA/genetic material is replicated and it becomes 2 times of the genetic material of the mother cell so that it can be equally distributed among the daughter cells in the cell division.
• The G2 phase is where the cell is prepared for the cell division where the protein and the enzymes required for the cell division are prepared or synthesized.
• Therefore the correct answer is option S phase.
