In gel electrophoresis, DNA fragments migrate toward the:

  1. Positive electrode
  2. Negative electrode
  3. Neutral region
  4. Center of the gel
Show answer and explanation

Correct answer: Positive electrode

DNA has a negatively charged phosphate backbone, so it moves toward the positive electrode during electrophoresis. This property enables its separation in an electric field.
