Vertebrate mtDNA code

The vertebrate mitochondrial DNA (mtDNA) genetic code

    Differences between the vertebrate mtDNA code and the "universal" code are indicated in red. Note that UGA codes for Trp rather than being a stop codon, there are two Met codons, and two AGR codons are read as Stops. Slightly different mtDNA codes are found in Drosophila and other invertebrate groups.
