Vedclass · Answer

(A) The process of post-transcriptional modification in eukaryotes involves three main steps:$1$. Splicing: The process of removing non-coding sequences called introns and joining the coding sequences called exons is known as splicing. Thus, $(a-3)$.$2$. Capping: In this process, an unusual nucleotide, methyl guanosine triphosphate, is added to the $5'$ end of the $hnRNA$. Thus, $(b-4)$.$3$. Tailing: In this process, adenylate residues (about $200-300$) are added at the $3'$ end in a template-independent manner. Thus, $(c-2)$.$4$. $mRNA$: After these modifications, the fully processed $hnRNA$ is called $mRNA$, which contains only exons. Thus, $(d-1)$.Therefore, the correct matching is $a-3, b-4, c-2, d-1$.
