  • AC and AA denote the tRNA anticodon and the amino acid specified, respectively.

  • (") indicates identity with the anticodon in the line above, and (–) indicates the lack of mitochondrially-encoded tRNAs with anticodons that can read the codons indicated at the left.

  • Deviations from the universal genetic code are set in bold italics.

  • Asterisks indicate termination codons.

  • Adenosines in the wobble position that are expected to be deaminated to inosine are represented in bold.
