[i] AC and AA denote the tRNA anticodon and the amino acid specified, respectively.

[ii] (") 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.

[iii] Deviations from the universal genetic code are set in bold italics.

[iv] Asterisks indicate termination codons.

[v] Adenosines in the wobble position that are expected to be deaminated to inosine are represented in bold.
