To compare a specimen using Gel electrophoresis, you must first take the DNA of a bald eagle and your specimen and separate the mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules must be separated and pushed by an electrical field through a gel that contains microscopic pores. The molecules travel through the tiny pores in the gel at a fast speed according to there length. This means that a small DNA molecule will travel a greater distance through the gel than will a larger DNA molecule. Next, you need to find the patterns that link the two DNA samples similarities. And if they are different in any way, this could lead to a new scientific discovery of a new
