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.
