Figure 3.
The result of subtraction of the DNA walk on the C strand from the DNA walk on the W strand for the third positions in codons (a) and the DNA walk on the W strand of intergenic sequences (b) of the T. pallidum genome. To make possible a quantitative comparison of a and b we have multiplied the values on the scale of y-axis for intergenic sequences—sequences that do not belong to any ORF longer than 70 codons—by a factor of 1.8 (the number of nucleotides in analyzed intergenic sequences was 1.8 times lower than the number of nucleotides in the third positions.
