The ranks of the true neighbours of IS5 elements in the E. coli genome. A, Experiment. B, Control. Rank of fluorescent intensities of target sequences as a function of their positions, relative to the position of an IS5 element. All known 11 locations of IS5 elements are shown as separate panels. The closed circles represent the IS5 elements and open circles represent the neighbours. The lower the rank, the higher probability that the gene is a neighbour of the IS5 element. Experiment and control are described in the legend to Figure 1 and in the text.
