Figure 2. Codon usage analysis of PCGs in the mitochondrial genome of Lontra longicaudis. All 20 amino acids [adenine (A), cysteine (C), aspartic acid (D), glutamic acid (E), phenylalanine (F), glycine (G), histidine (H), isoleucine (I), lysine (K), leucine (L), methionine (M), asparagine (N), proline (P), glutamine (Q), arginine (R), serine (S), threonine (T), valine (V), tryptophan (W), tyrosine (Y)] are listed by their one-letter abbreviations along the horizontal axis. Each amino acid comprises several codons that are listed and colour coded below their respective amino acid. The length of the coloured regions indicates the frequency of the respective codon within that amino acid. The vertical axis represents the RSCU values for the amino acids.
