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