Figure 12.
Shown here are fluctuations of duplex conformations around the first eigenvector direction, based on the PCA analysis of the backbone. (a) DNA-(CAG)4; (b) DNA-(GAC)4. Both duplexes have an initial anti-anti conformation. (Blue line) Most bending conformation; (red line) most unwinding conformation. To see this figure in color, go online.
