The correct answer is: If assertion is true but reason is false.
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.
