Question

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:

• A. Both Statement I and Statement II are incorrect
• B. Statement I is correct but Statement II is incorrect
• C. Statement I is incorrect but Statement II is correct.
• D. Both Statement I and Statement II are correct.

Answer 1

Answer: (C)

Statement I is incorrect but Statement II is correct.

Answer 2

Statement I: During G0 phase of the cell cycle, the cell is metabolically inactive.

• This statement is incorrect - While the G0 phase is considered a quiescent phase where cells are not actively dividing, many cells in G0 are still metabolically active and can carry out essential functions. Some cells in G0 are even more metabolically active than cells in other phases of the cell cycle.

Statement II: The centrosome undergoes duplication during S phase of interphase.

• This statement is correct - The centrosome does indeed undergo duplication during the S phase of interphase, specifically in preparation for cell division.

So, the correct option is (C): Statement I is incorrect but Statement II is correct.
