{{main|RNA splicing}}
The extensive processing of eukaryotic pre-mRNA that leads to the mature mRNA is the [[RNA splicing]], a mechanism by which [[intron]]s or [[outron]]s (non-coding regions) are removed and [[exon]]s (coding regions) are joined.<ref>{{cite journal | url=https://www.nature.com/articles/s41580-022-00545-z | doi=10.1038/s41580-022-00545-z | title=The physiology of alternative splicing | date=2023 | journal=Nature Reviews Molecular Cell Biology | volume=24 | issue=4 | pages=242–254 | pmid=36229538 | vauthors = Marasco LE, Kornblihtt AR }}</ref><ref>{{cite journal | url=https://www.nature.com/articles/s41576-022-00556-8 | doi=10.1038/s41576-022-00556-8 | title=Regulation of pre-mRNA splicing: Roles in physiology and disease, and therapeutic prospects | date=2023 | journal=Nature Reviews Genetics | volume=24 | issue=4 | pages=251–269 | pmid=36526860 | vauthors = Rogalska ME, Vivori C, Valcárcel J }}</ref>
