Ethidium Bromide is a chemical that will remove negative supercoils and 
introduce positive supercoils in circular DNA molecules. A number of sequential 
changes occur in the structure and electrophoretic properties of supercoiled 
plasmid DNA when increasing amounts of Ethidium Bromide are added. What will be 
the changes? Could you please help me. Thanks
