How Gel Electrophoresis Works

Gel Electrophoresis is a way to see DNA fragments separated by size. This process allows scientists to compare DNA to crime scenes, and to look for problems in DNA. The steps of Gel Electrophoresis are as follows:
1.Make sure there is enough sample DNA through the process of PCR
2.DNA is added to the container that holds the gel
3.Gel and DNA is submerged in liquid.
4. An electric current is passed through the liquid which allows the different sizes of DNA to move to different points in the container.
5.The gel and DNA is looked at under a UV light for analyzing.
