Figure 7From: Evolutionary paths of streptococcal and staphylococcal superantigensWindow analysis calculating dN/dS of selW . dN/dS was calculated as the ratio of nonsynonymous (dN) to synonymous (dS) substitution rates of gene pairs in selW from two MRSA genomes. The figure shows only the comparison of COL and MRSA252. The X-axis represents nucleotide position.Back to article page
