Universal scaling of the C-G distribution of genes

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.
