  1. 7MB, 4MB, 2MB, and 1MB

    Explanation:

    At the completion of the electrophresis, you wills see some bands appear. If the side you have put the sample is upper and the other the down part, the you will see from above to below are 7MB, 4MB, 2MB, and 1MB.

    This is due to the negatively charged molecules of DNA, so the bands moves from negative to positive sides.The negative side is the upper and the positive side is the lower side. Molecular do change the way bands are running. Heavier normally move slower than lighter bands.
