AIIMS 2019 Botany Transcription Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Assertion: In eukaryotes, transcription occurs in nucleus Reason: In bacteria, transcription and translation occurs in cytoplasm.

A

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

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Correct Answer

Option C

Detailed Explanation

The assertion is true because in eukaryotic cells, transcription occurs in the nucleus, where DNA is located, while the reason is also true as bacterial cells perform both transcription and translation in the cytoplasm due to the absence of a defined nucleus. However, the reason does not explain the assertion, as it pertains specifically to bacteria rather than eukaryotes, making option C the correct choice. Options A and B are incorrect because they imply a direct explanatory relationship between the assertion and reason, which does not exist, while option D is incorrect as both statements are true.
