spliceosomes
Spliceosomes are complex ribonuclear machines in eukaryotes that remove (splice out) the non-coding introns from primary transcript, precursor mRNA (pre-mRNA or hnRNA). Almost all eukaryotic protein coding genomes contain non-coding intervening sequences called introns.
Spliceosomes are variably composed of as many as 300 distinct proteins and five RNAs, making them among the most complex macromolecular machines known. Small RNA-protein complexes called small nuclear ribonucleoproteins (snRNPs, pronounced 'snurps') are essential components of the spliceosome.
