Examples of TA vs. GC skew plots for several bacterial species. Leading strand genes in blue, lagging strand genes in orange, intergenic segments flanked by genes in equal orientation in green, and intergenic segments flanked by genes in opposite orientations in red; circle area is proportional to segment length. Each plot displays skews in the range [− 0.5, 0.5]. Lower-left inset for each plot: average genomic G + C content for that species
