Vedclass · Answer

(D) Assertion $(A)$ is correct: In eukaryotes, the primary transcript, known as $hnRNA$ (heterogeneous nuclear $RNA$), is non-functional because it contains both coding sequences (exons) and non-coding sequences (introns). It must undergo splicing to remove introns and join exons to become functional $mRNA$.Reason $(R)$ is correct: In bacteria (prokaryotes), there is no defined nucleus, and transcription and translation occur in the same compartment (cytoplasm). Furthermore, bacterial $mRNA$ does not require complex processing like splicing because it lacks introns.Conclusion: While both statements are scientifically accurate, the Reason $(R)$ describes the nature of bacterial gene expression and does not explain why eukaryotic $hnRNA$ contains introns. Therefore, Reason is not the correct explanation of Assertion.
