Figure 3
Comparative analysis of helical twist and minor-groove width in SP-containing and non-SP-containing DNA structures. (a) The change in helical twist for non-SP-containing (black triangles) and SP-containing DNA (black squares) are plotted with respect to base pairs. (b) Minor-groove widths are shown in the absence (black triangles) and presence (black squares) of the spore photoproduct lesion plotted for dinucleotide steps (bases 5–12). |
