Eukaryotes encode long precursor RNA transcripts, which are spliced, polyadenylated and capped to produce a messenger RNA that can be translated.
|Capping||Nucleus||Guanosine is added to the 5' end of the mRNA for stability, transport and translation initiation.|
|Polyadenylation||Nucleus||The 3’ end of the RNA is cleaved and a Poly-A tail is added by the polyadenylation complex.|
|Splicing||Cytoplasm||During splicing, introns are excised and exons are ligated together by the very large spliceosome.|
