  1. The total number of codons is shown. The assignment of each codon was detected within a metazoan alignment using GenDecoder server v1.6 [41]. The reverse complements of the anticodons are marked by asterisks, deviations from the versatility rule [15, 16, 18] are underlined. One codon (question mark) could not be determined with certainty.
