Given are two statements. Statement 1: During G0 phase of cell cycle, the cell is metabolically inactive. Statement 2: The centrosome undergoes duplication during S phase of interphase. In the light of the above statements, choose the most appropriate answer from the options given below:
Answer: (D) Statement 1 is incorrect, but Statement 2 is correct. Answer: Statement 1 is incorrect, but Statement 2 is correct Solution: Cells in the quiescent stage (G0) remain metabolically active but no longer proliferate, so Statement 1 (G0 is metabolically inactive) is false.
- A.Both Statements 1 and 2 are correct
- B.Both statements 1 and 2 are incorrect
- C.Statement 1 is correct, but Statement 2 is incorrect
- D.Statement 1 is incorrect, but Statement 2 is correct✓
Correct Answer
(D) Statement 1 is incorrect, but Statement 2 is correct
Solution & Explanation
Answer: Statement 1 is incorrect, but Statement 2 is correct Solution: Cells in the quiescent stage (G0) remain metabolically active but no longer proliferate, so Statement 1 (G0 is metabolically inactive) is false. The centrosome undergoes duplication during the S phase of interphase, so Statement 2 is correct. Hence only Statement 2 is correct.
