The aggregation, arrangement and bonding together of proteins and RNA molecules to form a ribonucleoprotein complex. The joining together of exons from two different primary transcripts of messenger RNA (mRNA) via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced. 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. The cellular process by which a complex containing RNA and proteins is synthesized, aggregates, and bonds together. Includes the biosynthesis of the constituent RNA and protein molecules, and those macromolecular modifications that are involved in synthesis or assembly of the ribonucleoprotein complex. Formation of a quadruple snRNP complex composed of the spliced leader (SL) RNA along with the U4/U6-U5 tri-snRNP complex. Interactions that may facilitate this include a duplex between the SL and U6 RNAs and interactions between the U5 RNA and the exon sequence at the 5' splice site within the SL RNA. The aggregation, arrangement and bonding together of a set of macromolecules to form a complex, carried out at the cellular level.
