  • question_answer
    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

    Correct Answer: C

    Solution :

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