The primary mRNA transcript “matures” to a mature mRNA by undergoing capping, polyadenylation, and splicing. Firstly, the GTP cap is attached at the 5’ end of the transcript in order to increase ribosome attachment and stability. Secondly, a poly(A) tail is added at the 3’ end in order to protect the molecule from degradation. Thirdly, the spliceosome splices introns out from the transcript to create a mature mRNA.
