Fig. 4From: Analysis of secondary structural elementsĀ in human microRNA hairpin precursorsPlot of the number of the most frequently occurring 5ā bulges, 3ā bulges, and internal loops without considering closing base pairs in miRNA precursors and all other RNAs. (a) distribution in miRNAs. In each group, different colors indicate that the difference in the rate of occurrence is statistically significant. (b) comparison of miRNAs to highly expressed human RNAs and RNAs from other organisms. *, p <0.05; **, p <0.01; ***, pā<ā0.001Back to article page
