Figure 1From: Analysis of synonymous codon usage in Hepatitis A virusA plot of value of the first and second axis of each complete coding region in COA. The first axis (Æ’'1) accounts for 26.98% of the total variation, and the second axis (Æ’'2) accounts for 19.50% of the total variation. A): Each HAV complete coding region was divided by geographical area. B): Each HAV complete coding region was divided by genotype.Back to article page
