Also plotted is cross-sectional information of the electrostatic potential along the DNA axis (Fig. ). This data was obtained by associating each point on the potential surface to a bin representing a base sequence location based on the point's closest distance to a nucleotide pair of P atoms. Points within a bin corresponding to a base sequence location are averaged, and the error bars represent the distribution of the potential within a bin. Note that while this distribution is relatively large, the spread is roughly the same size across the DNA axis. The plot shows that for this static snapshot the DNA sequence along the center A-tract is negatively polarized due to the solvent interaction, suggesting the model can capture the physics of the solvent interaction for a relatively large DNA system. Note that in a fully dynamic system, the DNA and solvent configurations and their corresponding interactions will be highly variable due to rapid thermal motion.
