Questions & Step-by-Step Solutions

What is the purpose of staining the gel after electrophoresis?
  • Step 1: After running electrophoresis, the DNA or proteins are separated in the gel.
  • Step 2: The gel is clear and you cannot see the separated DNA or proteins without help.
  • Step 3: Staining the gel adds a color to the DNA or proteins.
  • Step 4: The color makes it possible to see where the DNA or proteins are located in the gel.
  • Step 5: This helps scientists analyze and understand the results of the electrophoresis.
