Vedclass · Answer

(A) $RNA$ processing (also known as post-transcriptional modification) is a series of events that occur after the transcription of $RNA$ from $DNA$. In eukaryotic cells,the primary transcript (pre-$mRNA$) undergoes several modifications before it is exported from the nucleus to the cytoplasm for translation. These modifications include: $1$. $5'$-capping: Addition of a $7$-methylguanosine cap to the $5'$ end. $2$. Polyadenylation: Addition of a poly-$A$ tail to the $3'$ end. $3$. Splicing: Removal of non-coding introns and joining of coding exons. Therefore,$RNA$ processing is an event that occurs after $RNA$ is transcribed.
