Structural similarity of RNA loops as a function of their sequence divergence. Left: hairpin loops, right: single-stranded segments. Structural similarity over sequence diversity resulting from pairwise structural and sequence comparisons among structures of the same length. Structural similarity is given by the normalized median RMSD (see text) and sequence dissimilarity is given as fraction of maximum Hamming distance. Dashed lines correspond to a logistic curve fit (see text).
