Schematic of the stem-loop structure of hsa-miR-20a. Red letters indicate the mature miRNA; blue letters indicate the mature miRNA*. Possible motifs in an RNA include internal loops, 5’ bulges, 3’ bulges, hairpins, and multibranch loops (not shown). The loops are named by the identity of unpaired nucleotides and base pairs (indicated by parentheses). The two sides of a bulge or an internal loop are indicated with a “/”
