Figure 2From: Clustering of classical swine fever virus isolates by codon pair biasRelative synonymous codon usage exemplified with three prototype CSFV isolates. The histograms show the frequencies of synonymous codon usage in per mille for the strains "Glentorf" [GenBank:U45478], "Koslov" [GenBank:HM237795], and "Euskirchen" [GenBank:GU233732]. The values were calculated using the ANACONDA 2.0 software.Back to article page
