An unusual gene from a Eukaryotic protozoan parasite that cause human diseases contains a “group I intron” that must be spliced out to form a mature mRNA that encodes a protein. If the entire exact DNA sequence (including the group I intron) for this gene is inserted into a prokaryote genome like E. coli, when E. coli tries to express this gene the resulting polypeptide sequence will be the same as when it is made in the parasite.
