Cell Cycle and Cell Division question

2023 · Q77

NEETBiologyCell Cycle and Cell DivisionMCQ+4 / −1

Given below are two statements:

Statement I : During G0 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. A
    Both Statement I and Statement II are incorrect.
  2. B
    Statement I is correct but Statement II is incorrect.
  3. C
    Statement I is incorrect but Statement II is correct.
  4. D
    Both Statement I and Statement II are correct.

Correct answer: C

Statement I is incorrect. The G0 phase is a state in the cell cycle in which cells exist in a quiescent or dormant stage. However, this does not mean that the cell is metabolically inactive. Rather, the cell maintains its normal functions but is not preparing for cell division.



Statement II is correct. During the S phase (synthesis phase) of interphase, DNA replication occurs, and the centrosome, which plays a key role in cell division, also duplicates. This prepares the cell for the later stages of the cell cycle, where the cell divides into two daughter cells.
