The effect of S-substitution on the O6 guanine site of a 13-mer DNA duplex containing a G:T mismatch is studied using molecular dynamics. The structure. dynamic evolution and hydration of the S-substituted duplex are compared with those of a normal duplex. a duplex with S-substitution on guanine. https://smokeysmountainfurnitureoutlets.shop/product-category/desk/
