wlad13 [49]3 years ago
6 0

Answer:

See the answer below

Explanation:

The addition of acid to a DNA causes a change in its absorbance because acids tend to destroy the covalent bonds that hold the base pairs in DNA together.

In other words, acids, especially at high concentrations, denatures DNA. Denatured DNAs exhibit hyperchromic reaction, that is, they show increased absorbance as a result of less interaction between the bases.
