IIRC, mitochondria have their own separate DNA code. Not the same coding scheme used in the rest of the cell.

Some have cited this as evidence that mitochondria aren't actually part of the cell, but are a symbiotic organism, from way back in time.

Mitochondria appear to be descended from bacteria and they function as energy factories for cells. This particular organism has mitochondria which lack DNA. I'll see if I can find the name of the organism for you.

Found this at wikipedia: "A few organisms, such as Cryptosporidium, actually have mitochondria which lack any DNA, presumably because all their genes have either been lost or transferred."
