Question:
During the cell cycle, DNA replication occurs in which phase?
During the cell cycle, DNA replication occurs in which phase?
Show Hint
Cell cycle phases:
G1 \(\rightarrow\) S (DNA replication) \(\rightarrow\) G2 \(\rightarrow\) M (mitosis).
S phase: DNA synthesis.
G1 \(\rightarrow\) S (DNA replication) \(\rightarrow\) G2 \(\rightarrow\) M (mitosis).
S phase: DNA synthesis.
Updated On: Aug 18, 2026
- G1 phase
- G2 phase
- M phase
- S phase
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
The cell cycle has different phases.
Each phase has specific events.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the phases of the cell cycle.
Step 3: Detailed Explanation:
The cell cycle consists of:
G1 phase (growth), S phase (DNA synthesis), G2 phase (preparation for mitosis), and M phase (mitosis).
DNA replication occurs in the S phase.
Thus, the S phase is the correct answer.
Step 4: Final Answer:
DNA replication occurs in the S phase.
Hence, the correct option is (D).
