Match List I with List II : List-I (Phase of cell cycle) A. G1 phase B. S phase C. G2 Phase D. M phase List-II (Activity) I. Actual cell division occurs II. Cell is metabolically active and continuously grows but does not replicate its DNA III. Synthesis of DNA occurs and the amount of DNA per cell doubles IV. Proteins are synthesized while cell growth continues Choose the correct answer from the options given below :
Answer: (D) A-II, B-III, C-IV, D-I. Answer: A-II, B-III, C-IV, D-I Solution: In G1 (A) the cell is metabolically active and grows but does not replicate its DNA (II); in S phase (B) DNA is synthesised and the amount of DNA per cell doubles (III); in G2 (C) proteins are synthesised while cell growth continues (IV); and M phase (D) is when actual cell division occurs (I).
- A.A-IV, B-I, C-II, D-III
- B.A-I, B-II, C-III, D-IV
- C.A-III, B-IV, C-I, D-II
- D.A-II, B-III, C-IV, D-I✓
Correct Answer
(D) A-II, B-III, C-IV, D-I
Solution & Explanation
Answer: A-II, B-III, C-IV, D-I Solution: In G1 (A) the cell is metabolically active and grows but does not replicate its DNA (II); in S phase (B) DNA is synthesised and the amount of DNA per cell doubles (III); in G2 (C) proteins are synthesised while cell growth continues (IV); and M phase (D) is when actual cell division occurs (I). This matches option (4); the distractors wrongly swap DNA synthesis or actual division across phases.
