RNA processing

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