(Top) Internal loop studied in this work. Boxed region is identical to natural sequence from B. mori. Nucleotides above and below duplex are a natural sequence that was changed for this study. (Bottom) Sequences of loops in Callosamia promethea, Samia cynthia, Coscinocera hercules, and Saturnia pyri (Kierzek et al. 2009). Nucleotides potentially in an AG pair are underlined.
