From: Human SARS-CoV-2 has evolved to reduce CG dinucleotide in its open reading frames
Percentages of codon usage in open reading frames of SARS-CoV-2. Usage of synonymous codons for eighteen amino acids (except methionine and tryptophan) and three stop codons are shown in the figure. Percentages of codons with A, T, G and C at codon position 3 are in yellow, brown, green and aqua blue background, respectively. Total number of codons for each amino acid is indicated at top of the percentage bar. Arrows indicate four codons that contain CG at positions 2 and 3.
