a process where the DNA is sorted. The sample of DNA is poured into a gel, such
as agarose. A charge is then applied to the gel with a charge on both ends. The charges are opposites, positive on the bottom and a negative charge on the top. The DNA has a very small negative charge on it which causes it to move to the
bottom. The larger pieces can not move as fast so the smaller pieces move to
the bottom and the larger pieces are stuck nearest to the top.
