Nucleosome stability and positioning of synthetic DNA sequences. A: Δls profiles (black line) of the eleven stable nucleosome-forming DNA sequences reported elsewhere [22]. In the panels, the name of the samples and their ΔG are reported. Dots with horizontal bars (146-bp long) mark positions of mapped nucleosomes. B: Δls profile of s601-sample at different values of helical rise for the step at position 83 of the sequence. The minimal value corresponds to the green curve, the mean value to the black curve and the maximal value to the red curve. C: Scatter plot of nucleosomal stability ΔG vs. degree of symmetry Δls.
