Abstract

Circular dichroism (CD) spectroscopy can be successfully used to study the assembly of homoguanylic and guanosine-rich oligonucleotides. The CD corresponding to the low-energy bands of the guanine spectrum in the 250-290 nm region is mainly determined by exciton interaction between the guanine chromophores; it gives information on the relative skew of G-quartets and on their distortion from the classical structure found in the four-stranded helix of poly(G). The handedness of the sugar-phosphate backbone can be deduced indirectly only if the conformation of the bases around the glycosyl bond is known.
