Question: 174 Given below are two statements:
Statement I: During \mathrm{G}_{0} phase of cell cycle, the cell is metabolically inactive.
Statement II: 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:
(1) Statement I is correct but Statement II is incorrect.
(2) Statement I is incorrect but Statement II is correct.
(3) Both Statement I and Statement II are correct.
(4) Both Statement I and Statement II are incorrect.
Answer: Option (2)
Explanation:
The \mathrm{G}_{0} phase is a quiescent stage in which cells are metabolically active but do not divide, so Statement I is incorrect.
During the S phase of interphase, DNA replication occurs and the centrosome also duplicates in preparation for cell division, so Statement II is correct.
Therefore, Statement I is incorrect but Statement II is correct.
