Free energy maps for single mismatches in RNA-CAG (r(5′-CCG-CAG-CGG)₂) and RNA-GAC (r(5′-GGC-GAC-GCC)₂). (a) (Ω, χ₁₄) map for RNA-CAG; (b) (Ω, χ₁₄) map for RNA-GAC; (c) (χ₅, χ₁₄) map for RNA-CAG; and (d) (χ₅, χ₁₄) map for RNA-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. The solid lines (black, red and green) describe three possible transition paths from B1 to A1. To see this figure in color, go online.
