Match List-I with List-II regarding the phases of the cell cycle. List-I List-II (A) G₁ phase (I) Quiescent stage (B) S phase (II) DNA replication (C) G₂ phase (III) Proteins are synthesised in preparation for mitosis (D) G₀ phase (IV) Metabolically active but does not replicate its DNA Choose the correct answer from the options given below:
Options
- A(A)-(IV), (B)-(II), (C)-(III), (D)-(I)
- B(A)-(III), (B)-(II), (C)-(IV), (D)-(I)
- C(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- D(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
Correct answer
A. (A)-(IV), (B)-(II), (C)-(III), (D)-(I)
Step-by-step solution
The correct matching of the cell cycle phases with their defining events is as follows: G₁ phase corresponds to the interval between mitosis and initiation of DNA replication. The cell is metabolically active and continuously grows but does not replicate its DNA. Hence, (A) matches with (IV). S phase (Synthesis phase) is the period during which DNA replication takes place. Hence, (B) matches with (II). G₂ phase is the phase where proteins are synthesised in preparation for mitosis while cell growth continues. Hence
