Characterization of duplex DNA including X:K pairs by circular dichroism (CD). The ellipticity is plotted versus the wavelength for 2X2K (long dash line), 3X3K (dash dot dot line) along with control sequences for GC (dotted line), and AT (solid line). All of the duplexes have CD spectra indicative of right-handed B-form DNA.
