General Information
Term mRNA splicing, via spliceosome ID (Ontology) GO:0000398 (Gene Ontology)
Definition The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced.[ ISBN:0198506732 ISBN:0879695897 ]
Also Known As "nuclear mRNA splicing, via spliceosome"
