Comparison of motif types found in human miRNA precursors, highly expressed human RNAs, and RNAs with known structures from various organisms. (a) plot of the number of each secondary structural motif in human miRNA precursors including 3’ bulges (n = 924), 5’ bulges (n = 1089), internal loops (n = 3860), hairpins (n = 1546), and multibranch loops (n = 17). (b) plot of the percentage of each motif within its motif type (for example, the percentage of 1-nucleotide bulges of total bulges). (c) plot of the percentage of each motif. Total motifs: human miRNA precursor, n = 7436; highly expressed human RNAs, n = 2712; all other RNAs, n = 26,213; *, p <0.05; **, p <0.01; ***, p < 0.001
