Question:
Which of the following represents the CORRECT order of events in the eukaryotic cell cycle?
Which of the following represents the CORRECT order of events in the eukaryotic cell cycle?
Show Hint
Easy mnemonic: “Grow → Synthesize → Grow again → Mitosis” = G1 → S → G2 → M.
Updated On: Sep 8, 2025
- G1 → S → G2 → M
- S → G1 → M → G2
- G1 → S → M → G2
- S → G1 → G2 → M
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall phases of cell cycle.
- G1 (Gap 1): Cell growth and preparation.
- S (Synthesis): DNA replication occurs.
- G2 (Gap 2): Further growth and preparation for mitosis.
- M (Mitosis): Chromosome segregation and cytokinesis.
Step 2: Compare sequences.
Only option (A) correctly follows the standard cell cycle order.
Final Answer: \[ \boxed{\text{Correct order is G1 → S → G2 → M.}} \]
- G1 (Gap 1): Cell growth and preparation.
- S (Synthesis): DNA replication occurs.
- G2 (Gap 2): Further growth and preparation for mitosis.
- M (Mitosis): Chromosome segregation and cytokinesis.
Step 2: Compare sequences.
Only option (A) correctly follows the standard cell cycle order.
Final Answer: \[ \boxed{\text{Correct order is G1 → S → G2 → M.}} \]
