Figure 2From: Quantitative analysis of replication-related mutation and selection pressures in bacterial chromosomes and plasmids using generalised GC skew indexDifference in GC skew strength between eubacteria and archaea. Plot of gGCSI (X-axis) and z-score (Y-axis) for chromosomes of 710 eubacteria (black crosses) and 53 archaea (red closed circles) with 512 windows. Most of the archaeal chromosomes are located in the lower left corner, where gGCSI < 0.1 and z-score < 5.Back to article page
