Answer:
Hence it's the acidic part of the molecule that dominates, and that is why we know DNA as an acid.
DNA is made of three types of molecules in equal proportions - basic nucleotides, sugar deoxyribose and acidic phosphate groups.
The bases are on the inside of the helix and partly hidden from the outside.
Yes, DNA is a weak acid, an organic and very weak acid, but it does exist in the cell as a salt, like other acids.
Hence it reacts with some weak bases and exists as salt in the ionic form. Hence it is stable in slightly alkaline pH (pH 8.0).
