Electrostatic free energy landscapes for nucleic acid helix assembly
Metal ions are crucial for nucleic acid folding. From the free energy landscapes, we investigate the detailed mechanism for ion-induced collapse for a paradigm system: loop-tethered short DNA helices. We find that Na(+) and Mg(2+) play distinctive roles in helix–helix assembly. High [Na(+)] (>0.3...
