15N-/14N-editing of the NMR resonances of imino protons for a sample of hybrid II in which the RNA strand was labeled with 15N at guanines. (A) All imino proton resonances. (B) 15N-editing: the observed resonances originate from guanine imino protons in the RNA strand. (C) 14N-editing: the observed resonances originate from imino protons of uracils/thymines and of guanines in the DNA strand.
