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.
The spliceosome is a complex of small nuclear RNA (snRNA) and small nuclear protein (snRNP) molecules, snRNAs and snRNPs.snRNPs include U1, U2, U4, U5 and U6.his removal is done in a coimplex protein structure called the spliceosome. The spliceosome splices out the non-coding introns from the primary mRNA transcript, and stiches the exons back together into the mature mRNA transcript.
