RNA splicing : ウィキペディア英語版 | RNA splicing
In molecular biology and genetics, splicing is a modification of the nascent pre-messenger RNA (pre-mRNA) transcript in which introns are removed and exons are joined. For nuclear-encoded genes, splicing takes place within the nucleus after or concurrently with transcription. Splicing is needed for the typical eukaryotic messenger RNA (mRNA) before it can be used to produce a correct protein through translation. For many eukaryotic introns, splicing is done in a series of reactions which are catalyzed by the spliceosome, a complex of small nuclear ribonucleoproteins (snRNPs), but there are also self-splicing introns. ==Splicing pathways== Several methods of RNA splicing occur in nature; the type of splicing depends on the structure of the spliced intron and the catalysts required for splicing to occur.
