    hn-RNA undergoes two additional processing. Out of which, in one of them an unusual nucleotide (methyl guanosine triphosphate) is added to the 5-end of hnRNA. This is known as

    A) capping                               

    B) tailing                   

    C)        splicing                

    D)        termination

    Correct Answer: A

    Solution :

    Heterogenous nuclear RNA (hnRNA) undergo two additional processing known as capping and tailing. In Caping an unusual nucleotide (methyl guanosinetriphosphate) is added to the 5 end of hnRNA. In tailing, a adenlate residues (200-300) are added at 3 end in template independent manner. In splicing, introns are removed and exons are joined in a definite order.
