Upon exposure to UV radiation, DNA stained with ethidium bromide will show
- A Bright orange colour
- B Bright red colour
- C Bright blue colour
- D Bright yellow colour
Answer & Solution
Correct Answer
(A) Bright orange colour
Step-by-step Solution
Detailed explanation
Option \((1)\) is the correct answer because in recombinant \(DNA\) technology the separated \(DNA\) fragments can be visualised only after staining the \(DNA\) with a substance known as ethidium bromide followed by exposure to \(U.V.\) radiation. You can see bright orange coloured bands of \(DNA\) in an ethidium bromide stained gel exposed to \(U.V.\) light.
