Correlation between G+C content and base composition of CDSs. The contents of four nucleotides in CDSd (upper panel) and CDSg (lower panel) in the 185 bacterial chromosomes are computed and plotted against their C+C content. The correlation coefficient for all the four trends are larger than 0.97. G content, red symbols; C content, red symbols; A content, blue symbols; T content, orange symbols.
