Figure 6

Plot of relative importance of G+C content in different codon positions in its correlation with OSC usage bias in the +2 frame (A) and the +3 frame (B). Note that the proportion of total variance explained, R2, is much smaller for the +3 frame (78.75%) than the +2 frame (91.81%), which is consistent with the PCA results shown in Additional File 1, Supplementary Figure 2.
