Size-expanded DNA bases: An ab initio study of their structural and electronic properties
Article Abstract:
Second-order Moller-Plesset perturbation theory and density functional theory (DFT) are used to investigate the structural and electronic properties of size-expanded DNA bases, xA, xC, xG, and xT, and their natural counterparts. The results show that natural and size-expanded bases have both nonplanar amino groups, but the latter also has nonplanar aromatic rings, and xG is easier to oxidize than G.

Interaction of thionin with DNA strands: intercalation versus external stacking
Article Abstract:
Interaction of thionin in a glycerol/water glass bound to DNA quadruplexes and DNA duplexes with pressure-tuning hole-burning spectroscopy at 2 k are investigated. Pressure-tuning hole-burning experiments using thionin as a probe and various short-stranded DNA chains as complex-forming partners are also reported.
