DNA fragments generated by the restriction endonucleases in a chemical reaction can be seperated by
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'
