Cell Cycle And Cell Division Question 2

Question: Given below are two statements:

Statement I: During Go 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 incorrect but Statement II is correct.

(2) Both Statement I and Statement II are correct.

(3) Both Statement I and Statement II are incorrect.

(4) Statement I is correct but Statement II is incorrect.

Show Answer

Answer: (2) Both Statement I and Statement II are correct.

Explaination-

S phase- the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

Go phase- cell is not actively preparing to divide, for some cells Go is a permanent state for some cells, while others may re-start division if they get the right signals.
