Webies (1-4). The structure of the hydration shell depends on the sequence and conformation of the DNA molecule and can play an important role in the stabilization of its three-dimensional structure. A well-known example is the spine of hydration, which originally was observed in the A+T-rich center of the DNA minor groove in the Drew dodecamer, Webthe hydration shell, while the structure breaking ions may squeeze through the DNA hydration shell to the groove bottom and form long-lived complexes with the atoms of nucleotide bases. The diﬀerence in the interaction of the structure making and the structure breaking counterions with the DNA double helix is explained by diﬀerent structure ...
