This page covers the process of transcription, along with the multiple types of RNA produced through this process. Special emphasis is given to messenger RNA (mRNA), including the modifications needed to produce this type of RNA.

It explains RNA processing's role in transforming pre-mRNA into mature mRNA, promoting mRNA stability, nuclear export, and translation initiation. RNA splicing involves removing introns and linking exons with spliceosome assistance, while polyadenylation entails adding a poly-A tail for mRNA stability.
