(Left) Comparison between competition constants obtained from experiment and 3D-RISM calculations. Experimentally derived estimates for the competition constant of K+ versus 10 mM Na+ do not exist. (Middle) Competition constants determined for a series of DNA (24L), RNA (R24L), DNA/RNA hybrid (H24L), triplex TDNA (T24L) constructs (see ‘Materials and Methods’ section for details) as well as dimethylphosphate (DMP). (Right) Overlay of charge-normalized ion competition profiles (Equation 9) for different nucleic acid constructs.
