The aggregation, arrangement and bonding together of the spliceosome, a ribonucleoprotein apparatus that catalyzes nuclear mRNA splicing via transesterification reactions. Recognition of both the 5' and 3'-splice sites and positioning them in the correct alignment with respect to each other so that the second catalytic step of nuclear mRNA splicing can occur. The aggregation, arrangement and bonding together of proteins and RNA molecules to form a ribonucleoprotein complex. Selection of a splice site by components of the assembling spliceosome. Recognition of the intron 3'-splice site by components of the assembling U2- or U12-type spliceosome.
