Figure 3
Comparison of GC 3 and GC-content of non-coding regions, and distribution of GC-content of non-coding regions. Two-dimensional plots show the correlation between the GC3 of genes and the GC-content of non-coding regions surrounding the genes in the Burmese python (A) and the correlation of the GC3 of the orthologs between the python and the rat snake (B). Frequency distributions of GC-content are shown as histograms for all the python non-coding regions (C), for the macrochromosomal regions (open columns) and the microchromosomal regions (black columns) (D).
