A.2Effect ofLowHydrationandDecreased IonContent
HelicalParameters inMicrohydratedDNA
TableA.1: Helical parameters of the PolyA DNA species in microhydrated environ-
ment in comparison with the values for DNA in bulk solution. Helical
parameterswere calculated alongMDsimulations, andmean valueswith
standarddeviation are presented for each base-pair step.
