Option D
Solution
Coding sequences or expressed sequences that appear in mature or processed $RNA$.
Intervening sequences which do not appear in mature or processed $RNA$. They only interrupt exons.
– In capping an unusual nucleotide (methyl guanosine triphosphate) is added to the $5^{\prime}$-end of $hnRNA$.
In tailing, adenylate, residues ($200$-$300$) are added at $3^{\prime}$-end in a template independent manner.
