Circular dichroism spectroscopy indicates that C9 40-mer RNA lacks the hallmarks of G-Q structures and has a CD spectrum matching that of a designed hairpin structure. (AC) C9 40-mer RNA. (DF) TERRA 24-mer RNA. (GI) Hairpin no-G-Q 40-mer RNA. The first column of spectra shows the cation dependence; 100 mM KCl, 100 mM LiCl and no added salt, all at 20°C. The second column shows the temperature dependence of the CD spectra in KCl. The third column shows the melting curves in three different ionic conditions.
