mRNA trans splicing, SL addition
nuclear mRNA trans splicing, SL addition
exact
nuclear mRNA trans splicing, spliced leader addition
exact
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.
