Sequence and putative secondary structures of two human miRNA stem–loops from the let-7 family (SL-let-7a-1 and SL-let-7g) and a control (dlet-7g) that only contains the RNA duplex portion of the SL-let-7g RNA (Desjardins et al. 2011). Residues that are part of the mature miRNAs are labeled in red within SL-let-7a-1 and SL-let-7g. Uppercase and lowercase letters indicate residues that are, respectively, present and not present in the natural RNAs.
