So we now place the fragments onto the corner of a sheet and we run electrophoresis along the horizontal direction. So essentially we place them onto the corner and they begin to migrate. And once again the ones that are heaviest, the ones that are largest will essentially migrate the least. And so because fragment three is the largest this will basically travel the least distance. And because fragment two is the smallest it will travel the greatest distance. And then four is slightly smaller than what is it one.
