WebRNA chains fold back on themselves to form hairpin loops or stem-loops, so that these sequences can form helices. Many of the helical stems in RNA hairpins are interrupted by internal loops, which is to say regions where sequences are juxtaposed that can-not form GCs, AUs, or wobble GUs, which most regard as “honorary” Watson-Crick base pairs.
