Assertion : In eukaryotes, both intron and exon are transcribed to form hnRNA.
Reason : Splicing is required in prokaryotes.
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
C. If assertion is true but reason is false.
Step-by-step solution
Eukaryotic transcripts possess extra segments called introns or intervening sequences or non-coding sequences. They do not appear in mature or processed RNA. The functional coding sequences are called exons. Splicing is removal of introns and fusion of exons to form functional RNAs. Splicing is generally not required in prokaryotes.
