Transcription in eukaryotes occurs within the nucleus and mRNA moves out of the nucleus into the cytoplasm for translation. The mRNA is processed from the primary RNA transcript. This is called post transcriptional processing. This includes capping (7mG cap) at 5' end, tailing (poly A tail) at 3' end and splicing (removal of introns and joining of exons in a defined order). The primary mRNA transcript is longer and localised into the nucleus, where it is also called heterogenous nuclear RNA (hnRNA) or pre-mRNA. It has both exons and introns.
