Question #23189

Answer 1

Since it donates Protons!

Explanation:

Here, it is all about Chemistry.

I'm sure that You will know that DNA is made up of Nucleotides .

A nucleotide is made up of Nucleoside and a Phosphate Group.

They continuously connect to form the DNA as a polymer by Phosphodiester bond.

Here, DNA is acidic due to the presence of Phosphoric acid (`H_3PO_4` ) which loses one hydrogen as a proton ( `H^+` ) because it was dissolved in a basic environment inside the nucleus.

As we know an acid will only dissolve in a base by losing a proton `(H^+)`.
