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.
Simple illustration of exons and introns in pre-mRNA and the formation of mature mRNA by splicing. In molecular biology and genetics, splicing is a modification of the nascent pre-messenger RNA (pre-mRNA) transcript in which introns are removed and exons are joined. For nuclear-encoded genes, splicing takes place within the nucleus after or concurrently with transcription.
