DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by Centrifugation, Polymerase chain reaction, Electrophoresis, or Restrictions mapping?

Electrophoresis is a technique used in the laboratories in order to separate macromolecules (DNA, RNA) based on size. The technique applies a negative charge so proteins move towards a positive charge. This is used for both DNA and RNA analysis. So, the DNA fragments generated by restriction endonucleases in a chemical reaction can be separated by this process of gel electrophoresis. So the correct answer is 'Electrophoresis'
