Biophysical characterization of ZGQs

(A) CD spectra analysis of ZGQs showing parallel RNA topology in the presence of cations, namely, K+, Na+, Li+, and Mg2+. (B) 1H NMR spectra analysis of the ZGQs showing the signature imino proton peaks in the predicted four ZGQs, thus confirming the Hoogsteen bond formation in GQ structure.
