(1) Heterogeneous nuclear RNA (hnRNA) undergo two additional processing known as capping and tailing. In Capping 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, intorns are removed and exons are joined in a definite order.
