Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. The joining together of exons from one or more primary transcripts of nuclear messenger RNA (mRNA) and the excision of intron sequences, 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 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 from two different genes, each of which also produces mRNA(s) via cis-splicing. Splicing of RNA via a series of two transesterification reactions with a bulged adenosine residue from the intron branch point as the initiating nucleophile. When the initial RNA for the splicing reaction is a single molecule (cis splicing), the excised intron is released in a lariat structure.
