Figure 5From: In silico genetic robustness analysis of microRNA secondary structures: potential evidence of congruent evolution in microRNACorrelation between Z -scores and P-values of environmental robustness for all the 1,082 miRNAs. For each real pre-miRNA, the free energy is compared with that of 1,000 random sequences (a) and random pseudo pre-miRNAs (b), and the Z-score and P-value are computed. The curve for a normal distribution of mean 0 and a standard deviation of 1 is also displayed.Back to article page
