WebThe spliceosome is a cellular machine that removes introns from gene transcripts to generate mature messenger RNA. It forms by a dynamic assembly of five structured RNAs – the U-rich small nuclear RNAs: U1, U2, U4, U5 and U6- and many proteins. What are the two components of spliceosomes How do spliceosomes work? Abstract. A spliceosome is a large ribonucleoprotein (RNP) complex found primarily within the nucleus of eukaryotic cells. The spliceosome is assembled from small nuclear RNAs (snRNA) and numerous proteins. Small nuclear RNA (snRNA) molecules bind to specific proteins to form a small nuclear ribonucleoprotein complex (snRNP, pronounced “snurps”), which in turn combines with other snRNPs to fo…
