RNA Splicing
Definition 1
Removal of introns from mRNA precursors and the reattachment or annealing of exons. (NCI Thesaurus)
Definition 2
The process by which introns, the noncoding regions of genes, are excised out of the primary messenger RNA transcript, and the exons (i.e., coding regions) are joined together to generate mature messenger RNA. The latter serves as the template for synthesis of a specific protein. (NCI Dictionary)
Definition 3
The ultimate exclusion of nonsense sequences or intervening sequences (introns) before the final RNA transcript is sent to the cytoplasm. (NLM, Medical Subject Headings)
