Figure 1From: Codon usage in vertebrates is associated with a low risk of acquiring nonsense mutationsGenetic code and risk of acquiring nonsense mutations. The codons of the standard genetic code are listed along with the 20 amino acids and the three stop codons. A risk score ω is shown as ω = 0 (yellow), ω = 1 (orange), and ω = 2 (red). The list is sorted according to the mean risk of the codons encoding a specific amino acid.Back to article page
