Multiple choice

What is Hyperchromic effect of DNA?

  1. Increase in the absorption of light at 260 nm as the DNA becomes denatured is known as Hyperchromic effect.

  2. Absorption of light at 260 nm by DNA is known as hyperchromic effect.

  3. DNA denaturation with the increase in temperature is known as hyperchromic effect.

  4. Both the options (1) and (2)

  5. None of these

A Correct answer
Explanation

Denatured DNA have less constrained bases compared to stacked bases of double stranded DNA. So, the denatured DNA will show more absorption of light. Hence, this option is the correct answer.
