Hydration forces between parallel DNA double helices: computer simulations.

M R Reddy1, M Berkowitz.   

Abstract

We have performed two molecular dynamics computer simulations of two 10-base-pair segments of DNA molecules immersed in water. The goal of these simulations is to study the structural and dynamical properties of water between the DNA molecules. We have observed water ordering next to DNA surfaces. Existence of such ordering was proposed earlier by Marcelja and Radic [Marcelja, S. & Radic, N. (1976) Chem. Phys. Lett. 42, 129-130] to explain strong hydration forces between macromolecular surfaces.
