Figure 1
Positional autocorrelation of CG dinucleotides in different isochores of the human genome. The normalized histograms of occurrences of the dinucleotide pairs at distances 2-80 bases from one another are shown. The histograms are smoothed by running average of 3 positions. The level 1.00 corresponds to the average counts within the interval 0-80 (53.5 × 103 for H3, 92.0 × 103 for H2, 74.8 × 103 for H1, 45.5 × 103 for L2 and 9.5 × 103 for L1). The 10.4 base periodical distances are shown by vertical bars.
