  • alternative splicing — the splicing of RNA at variable positions on the primary transcript as a function of the type of tissue or of the developmental stage, removing varying introns to yield distinct mRNA s that encode specific proteins; it is a mechanism for… …   Medical dictionary

  • RNA splicing — In molecular biology and genetics, splicing is a modification of an RNA after transcription, in which introns are removed and exons are joined. This is needed for the typical eukaryotic messenger RNA before it can be used to produce a correct… …   Wikipedia
