(a) UV-vis spectra of 2•3 and 2t•3t in the presence and absence of Zn(II) (b) Thermal denaturing of the DNA strands 2•3, 2t•3t and of 2t•3t in the presence of 0.5 eq Zn(II). (c) CD spectra of 2•3 and 2t•3t, both in the presence and absence of Zn(II). Conditions for the measurements: 2 μM DNA in 100 mM NaCl, 50 mM phosphate buffer pH 7.0; the CD measurements were done at 4 μM concentration.
