Assertion: The whole chromatin is not functional. Reason :...
Assertion: The whole chromatin is not functional.
Reason : Heterochromatin does not take part in transcription.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
The whole chromatin present in the nucleus is not functional because only a portion of chromatin called euchromatin takes part in transcription or RNA formation and hence protein synthesis. Heterochromatin does not possess active genes to take part in transcription.
