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.
Splicing is the name given to the reaction that removes unnecessary segments of the primary RNA transcript, called introns. The removal of the introns produces mRNA (see the figure, below). Messenger RNA contains only exons, those portions of the primary RNA transcript that will be translated into a protein.
