Fig. 3From: Codon usage of host-specific P genotypes (VP4) in group A rotavirusENC-plot analysis of VP4 coding sequences for the eight RVA P genotypes. The ENC values were plotted against the GC contents at the third codon position (GC3). The expected curve represented the expected ENC values according to corresponding GC3 contents. The dots represented VP4 sequencesBack to article page
