They do this by alternative splicing (AS). Alternative splicing means, that during the RNA splicing event different combinations of exons can be joined together to create a diverse array of mRNAs from a single pre-mRNA. When these are translated they produce different proteins which do different things.
A spliceosome is a large and complex molecular machine found primarily within the splicing speckles of the cell nucleus of eukaryotic cells. The spliceosome is assembled from snRNAs and protein complexes. The spliceosome removes introns from a transcribed pre-mRNA, a kind of primary transcript.This process is generally referred to as splicing.he RNA component of the small nuclear ribonucleic protein or snRNP (pronounced snurp) is rich in uridine (the nucleoside analog of the uracil nucleotide). The canonical assembly of the spliceosome occurs anew on each hnRNA (pre-mRNA).
