Fig. 1

Comparison between computationally estimated J factors and experimentally derived J factors. A panel is provided for each of the seven sets of curated structural parameters (Table 1). In each panel, the computationally estimated J factors of 86 DNA fragments are plotted using filled squares with a color reflecting the set of structural parameters that was used to derive them. In all panels, the experimentally measured J factors for the same 86 DNA sequences are shown as red circles. All horizontal axes are depicted using the same scale and reflect the length of the plotted DNA fragments. Similarly, all vertical axes are shown using identical logarithmic scales and reflect the values of either computationally estimated or experimentally derived J factors. The black line in all panels reflects J factors estimated based on the model of straight DNA. For clarity, computationally estimated J factors with values lower than 10⁻¹⁵ are shown as 10⁻¹⁵
