Fig. 7From: Degeneracy and genetic assimilation in RNA evolutionFrequency distribution of the neutrality of inverse folds of Phenylalanine. The same set of sequences is used as in Fig. 6. The x-axis is scaled by the square root. We compute the percentage of neutral neighbors of each such sequence with respect to Phe-tRNA i.e. the percentage of one point mutants that have Phe-tRNA structure in their MFE sets (blue bars). The distribution of neutral neighbors for the degenerate inverse folds of Phe-tRNA is depicted by the yellow bars. Most of the inverse folds of low neutrality are degenerateBack to article page
