NEET (UG) 2023 — Question 96
Upon exposure to UV radiation, DNA stained with ethidium bromide will show
- Option A:
Bright blue in colour
- Option B:
Bright yellow colour
- Option C:Correct
Bright orange colour
- Option D:
Bright red colour
Answer: C
Step-by-step solution
Option (3) 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.
