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.
Figure 1: Pre-mRNA splicing. Splicing of a pre-mRNA molecule occurs in several steps that are catalyzed by small nuclear ribonucleoproteins (snRNPs). After the U1 snRNP binds to the 5â² splice site, the 5â² end of the intron base pairs with the downstream branch sequence, forming a lariat.igure 1: Pre-mRNA splicing.
