Question

Which of the following is correct regarding RNA processing?

• A. In capping, methyl guanosine triphosphate is added to 3 and of hn RNA
• B. RNA polymerase-1 transcribes? RNA in eukaryotes
• C. In tailing, adenylate residues are added at 3end of hn-RNA
• D. Three types of RNA polymerase catalyse the transcription of these different types of RNAs in most bacteria

Answer 1

Answer: (C)

Capping of the pre-mRNA involves the addition of $7$-methylguanosme $(m^{7}G)$ to the $5$end. Whereas in tailing, adenylate residues are added at $3$ end of hnRNA.
