Gel electrolphoresis

 Gel Electrophoresis is what they use to sequence Dna.   They sequence the Dna by putting drops of it in the slits at the end the gel. then run a charge through the gel and after about half hour r so the positive charged Dna runs down the medium (gel) and any negative charged Dna moves opposite direction. In this lab i learned how to use gel electrolysis  to sequence Dna. Although we only used die.
