Genome-wide tendencies of Frequency Ratios. (A) Histogram of FR values for all PWM pairs in the genomic set of mouse promoter sequences. (B,C,D) Plots of GC content differences as a measure of PWM-to-PWM dissimilarity (Y-axis) versus FR values (X-axis, same as in A), for all promoters (B), CpGhigh promoters (C), and CpGlow promoters (D).
