Abstract
Comparison of the human mitochrondrial DNA sequence of the cytochrome oxidase subunit II gene and the sequence of the corresponding beef heart protein shows that UGA is used as a tryptophan codon and not as a termination codon and suggests that AU A may be a methionine and not an isoleucine codon. The cytochrome oxidase II gene is contiguous at its 5′ end with a tRNAAsp gene and there are only 25 bases at its 3′ end before a tRNALys gene. These tRNAs are different from all other known tRNA sequences.
