Why does DNA move towards the positive electrode in Agarose gel electrophoresis?

Why does DNA move towards the positive electrode in Agarose gel electrophoresis?
  1. DNA is positively charged
  2. Agarose gel is positively charged
  3. DNA is negatively charged
  4. Agarose gel is negatively charged

Solution

DNA is a negatively charged molecule, so it moves towards the positive electrode (anode) during Agarose gel electrophoresis.
