Question: What is a common method for visualizing DNA after gel electrophoresis?

Options:

  1. Fluorescent microscopy
  2. Ethidium bromide staining
  3. Western blotting
  4. Southern blotting

Correct Answer: Ethidium bromide staining

Solution: 

Ethidium bromide staining intercalates with DNA and fluoresces under UV light, allowing visualization of DNA bands.

Questions & Step-by-Step Solutions

What is a common method for visualizing DNA after gel electrophoresis?
Correct Answer: Ethidium bromide staining
  • Step 1: After performing gel electrophoresis, the DNA is separated in the gel.
  • Step 2: Ethidium bromide is added to the gel. This is a special dye that can attach to DNA.
  • Step 3: The gel is then exposed to ultraviolet (UV) light.
  • Step 4: When the UV light shines on the gel, the ethidium bromide that is attached to the DNA glows.
  • Step 5: This glowing allows us to see the DNA bands clearly.
  • Gel Electrophoresis – A technique used to separate DNA fragments based on size.
  • DNA Visualization – Methods used to make DNA bands visible after separation.
  • Ethidium Bromide – A fluorescent dye that intercalates with DNA and is used for staining.
