- DNA can be seen in visible light.
- DNA can be seen without staining in visible light.
- Ethidium bromide stained DNA can be seen in visible light.
- Ethidium bromide stained DNA can be seen under UV light.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Ethidium bromide is a fluorescent dye that binds to DNA. When exposed to UV light, it fluoresces, making the DNA bands visible after separation by agarose gel electrophoresis.
