<P> Splicing is catalyzed by the spliceosome , a large RNA - protein complex composed of five small nuclear ribonucleoproteins ( snRNPs , pronounced ' snurps ' ) . Assembly and activity of the spliceosome occurs during transcription of the pre-mRNA . The RNA components of snRNPs interact with the intron and are involved in catalysis . Two types of spliceosomes have been identified ( major and minor ) which contain different snRNPs . </P>
