From: Separate base usages of genes located on the leading and lagging strands in Chlamydia muridarum revealed by the Z curve method

Figure 1

The distribution of points based on the two most important axes using the correspondence analysis of the nine variables u1u9 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.
