a. there is an electric charge in gel (+) at the top, which repels the (+) DNA molecules
b. there is an electric charge in gel (-) at the top, which repels the (+) DNA molecules
c. there is an electric charge in gel (-) at the top, which repels the (-) DNA molecules
d. there is an electric charge in gel (+) at the top, which repels the (-) DNA molecules
