Question

Which one of the following figures represents the correct sequence of phases in adult eukaryotic cell cycle? 

• A. A
• B. B
• C. C
• D. D

Hint:

Remember that the typical sequence of phases in the eukaryotic cell cycle is: G1 → S → G2 → M.

Answer 1

The Correct Option is B

Step 1: Understanding the cell cycle.
The phases of the eukaryotic cell cycle include G1, S, G2, and M. The correct sequence of these phases is essential to understanding how cells divide and replicate. The S phase is where DNA replication occurs, G1 and G2 are growth phases, and M is mitosis.
Step 2: Analyzing the options.
The figure representing the correct sequence follows the order of G1, S, G2, M.
(A) Figure A: Incorrect. The sequence does not follow the typical order.
(B) Figure B: Correct — This shows the correct sequence of phases: G1 → S → G2 → M.
(C) Figure C: Incorrect. The order is reversed in some places.
(D) Figure D: Incorrect. This is not the correct order.
Step 3: Conclusion.
The correct answer is (B) Figure B, as it shows the correct order of phases in the cell cycle.
