1.	Assertion (A) Transcription unit is often monocistronic in eukaryotes and polycistronic in prokaryotes Reason (`R`) Exons do not appear in mature RNA, introns appear is mature RNA.A. A and R are true and R is correct explanation of AB. A and R are true, but R is not correct explanation of AC. A is true, but R is falseD. A is false, but R is true
Answer» Correct Answer - C During the RNA splicing introns are removed and exons are joined to form a contiguous coding. This make mature mRNA ready for translation Eukaryotic mRNA moleculea are monocistonic containing the coding sequence only for one polypeptide In prokaryotes an individual bacterial mRNA molecules are polycistronic having transcripts of several genes
