Why are DNA acidic in nature?

Answer 1

DNA is made up of nucleotides ,which are the esters of phosphoric acid;at cellular pH values ,the phosphates are present as salts. So,they are called as acids.

Answer 2

DNA is acidic in nature because it contains phosphate groups in its backbone. These phosphate groups have a negative charge, making DNA an acidic molecule. The presence of acidic phosphate groups allows DNA to easily interact with positively charged molecules during processes like DNA replication and protein synthesis.

Answer 3

the phosphate ion in the dna structure makes it acidic.
