Figure 6From: Quantitative analysis of mutation and selection pressures on base composition skews in bacterial chromosomesRAP and TAP at the three positions of codons. σGR, σAR, σGT, and σATat three positions of codons (y-axis) are plotted against the overall σGR, σAR, σGT, and σAT, respectively (x-axis). Red, position 1; green, position 2; blue, position 3. The linear regression trend lines for each position are depicted.Back to article page
