Vedclass · Answer

(B) In eukaryotic cells,the primary transcript (pre-$mRNA$) undergoes post-transcriptional modifications to become mature $mRNA$. $1$. Capping: $A$ $7-methyl$ guanosine $(m^7G)$ cap is added to the $5'$ end of the transcript. $2$. Tailing: $A$ poly-$A$ tail (a sequence of adenine nucleotides) is added to the $3'$ end. $3$. Splicing: Introns are removed,and exons are joined together. These modifications protect the $mRNA$ from degradation and facilitate its transport and translation. Therefore,the presence of a $5'$ cap and a $3'$ poly-$A$ tail is the hallmark of a mature eukaryotic $mRNA$.
