Vedclass · Answer

(A) In eukaryotic cells,the primary transcript $(hnRNA)$ undergoes post-transcriptional modifications to become functional $mRNA$.$1$. Tailing (Polyadenylation): In this process,$200-300$ adenylate residues are added at the $3'$ end of the $hnRNA$ in a template-independent manner.$2$. Capping: In this process,an unusual nucleotide,methyl guanosine triphosphate,is added to the $5'$ end of the $hnRNA$.$3$. Splicing: In this process,the non-coding sequences (introns) are removed,and the coding sequences (exons) are joined in a defined order.Therefore,tailing involves the addition of adenylate residues at the $3'$ end.

In processing of eukaryotic $hnRNA$,during protein synthesis,tailing involves . . . . . . of $RNA$.
