Assertion: In plant cells, during S-phase, DNA replication begins in the nucleus, and the centriole duplicates in the cytoplasm.
Reason: If the initial amount of DNA is denoted as 2n in `G_(1)` even after S-phase the amount of DNA remains the same i.e., 2n.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
In animal cells ,during S-phase ,DNA replication begins in the nucleus ,and the centriole duplicates in the cytoplasm.
If the initial amount of DNA is denoted as 2n at g1, even after S-phase the amount of DNA does not remains the same i.e, 4n
