Figure 10From: In silico genetic robustness analysis of microRNA secondary structures: potential evidence of congruent evolution in microRNADistribution of Z -score of genetic and environmental robustness. 3D histogram plots of Z-scores of genetic and environmental robustness. The Z-scores are obtained by comparing the robustness of real pre-miRNAs with that of 1,000 random sequences (a) and random pseudo pre-miRNAs (b).Back to article page
