Given here are free energy maps for single mismatches in DNA-CAG (d(5′-CCG-CAG-CGG)2) and DNA-GAC (d(5′-GGC-GAC-GCC)2). (a) Shown here are: (Ω, χ14) map for DNA-CAG; (b) (Ω, χ14) map for DNA-GAC; (c) (χ5, χ14) map for DNA-CAG; and (d) (χ5, χ14) map for DNA-GAC. The letters represent the local minima, with associated structures as shown in Fig. 2 and free energy values given in Table 1. The primed letters represent minima that are mirror images of minima labeled with the corresponding unprimed letters. To see this figure in color, go online.
