Fig. 2From: Computational analysis of envelope glycoproteins from diverse geographical isolates of bovine leukemia virus identifies highly conserved peptide motifsSliding window analysis based on the rate of DNA polymorphism and divergence in synonymous sites and non-synonymous sites. Values shown on the y-axis are the ratio of the rate of non-synonymous substitutions dN to the rate of synonymous substitutions dS at each nucleotide position calculated using the following sliding window options: window length: 9, step size: 3. The segments analyzed were: a 202–237 (segment G), b 856–903 (segment H), c 238–277 (segment I), d 394–432 (segment J), e 136–153 (segment K). Nucleotide positions were numbered beginning with the adenosine residue in the first position of the ATG start codon of the gp51 coding sequenceBack to article page
