FIG. 7.

Comparison of nucleotide and amino acid sequence variability within HPV45 genes and the URR. a, numbers and percentages of positions showing nucleotide variations; b, numbers of nucleotide variations, including multiple changes per position (the genes containing multiple variation changes are highlighted in bold); c, numbers and percentages of variable codons; d, numbers and percentages of changed amino acid positions per total amino acid/codon in each ORF (nonsynonymous changes); e, numbers and percentages of synonymous/silent changes per total amino acid/codon in each ORF; f, ratios of the numbers of nonsynonymous changes to the numbers of synonymous changes per codon; g, each nucleotide position is only counted once. nuc., nucleotide.
