5) The electrophoresis apparatus creates an electrical field with a positive electrode at one end of
the gel and a negative electrodes at the other end of the gel.
a) Which direction will DNA molecules migrate in the gel (+  – ) or (–  +)?

b) Explain why DNA molecules migrate in the direction you chose in part a.

c) Which DNA size fragment (large vs. small) would you expect to move toward the
opposite end of the gel most quickly? Explain your answer.
