The distribution of points based on the two most important axes using the correspondence analysis of the nine variables u₁ – u₉ for 909 genes of the C. muridarum genome. The genes transcribed on the leading strand are denoted by crosses, whereas the genes located on the lagging strand are denoted by open circles. The partition between the two categories of points in the plot shows that the genes located on the two strands of replication have separate base usages.
