name: nuclear mRNA trans splicing, SL addition
namespace: biological_process
type: go
obsolete: False

Description: The joining together of two independently transcribed RNAs, where the one that provides the 5' portion of the final mRNA is from a splice leader RNA (SL-RNA). The SL-RNA, or mini-exon donor sequence, is added to the 5'-end of the acceptor RNA molecule which provides the mRNA body.
