Universal scaling of the C–G distribution of genes Original Research Article

Using our previous result that the C–G distribution in genomes is very broad, varying as a power law of the size of the block of genome considered, we examine the C–G distribution in genes themselves. We show that the widths of the C–G distributions for the genes of several simple organisms also vary as power laws. This suggests that the power law behavior gives a universal scaling whereby the distributions for the C–G content of the genes from all species are mapped onto a single function.
