You mean like in metazoan mitochondria? See David Wolstenhome's 1992
review in Int'l Rev of Cytology 141:173; for yeast see Bonitz 1980 PNAS
77:3167.
If it is organelle codes you're interested in, I'd be interested to know
whether variants are used in other systems, e.g. plant mtDNA or cpDNA,
fungal mtDNA, etc.
Regards, Dan.
