Which one of the following statements is correct in the context of observing DNA separation by agarose gel electrophoresis?
Show Hint
Ethidium bromide is widely used in molecular biology for visualizing DNA under UV light during gel electrophoresis.
Updated On: Jan 13, 2026
- 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.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Role of ethidium bromide.
- Ethidium bromide is a dye used to stain DNA in agarose gel electrophoresis.
- It binds to DNA and fluoresces under UV light, making DNA bands visible.
