Deoxyribonucleic Acid is made up of a sugar (the deoxyribose), a phosphate ion, and a nitrogenous base. 

the phosphate ion is where the acidity is, its also called phosphoric acid while in your cells. 

You could argue that wouldn't it be equal with base and acidity with the nitrogenous base, but the acid is so much powerful then the base, the base is there just basically for supporting the deoxyribose
