title: The molecular electrostatic potential and steric accessibility of poly (dA-dT). poly (dA-dT) in various conformations: B-DNA, D-DNA and 'alternating-B' DNA.
abstract: The influence of conformational changes on the molecular electrostatic potential and the steric accessibility of the double stranded polynucleotide poly (dA-dT). poly (dA-dT) are investigated by calculating these properties for three different conformations : B-DNA, D-DNA and alternating-B DNA.
