abstract：:We present a study of how substituent groups of naturally occurring and modified nucleotide bases affect the degree of hydration of right-handed B-DNA and left-handed Z-DNA. A comparison of poly(dG-dC) and poly(dG-dm5C) titrations with the lipotropic salts of the Hofmeister series infers that the methyl stabilization ...
