Molecular dynamics simulation of (a) choline ions solvating the minor groove of A–T base pairs of duplex DNA; carbon atoms of choline ions are represented in yellow, oxygen atoms of choline ions are represented in red, and hydrogen atoms are in white. (b) Atomic-scale representation of the DNA–choline bonds. Adapted with permission from Nakano, M.; Tateishi-Karimata, H.; Tanaka, S.; Sugimoto, N.
