| Popis: | The influence on the molecular electrostatic potential of a B-DNA double helix of the screening of its phosphates by sodium and methylammonium cations is described. The effects of these two counterions are compared with respect to changes in the global potential of DNA and with respect to the potential minima at the nucleophilic sites of the purine and pyrimidine bases. |
