General Information

Term

regulation of RNA splicing

ID (Ontology)

GO:0043484 (Gene Ontology)

Definition

Any process that modulates the frequency, rate or extent of RNA splicing, the process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.
