WebAgarose gel electrophoresis is one of several physical methods for determining the size of DNA. In this method, DNA is forced to migrate through a highly cross-linked agarose matrix in response to an electric current. In solution, the phosphates of the DNA are negatively charged, and the molecule will therefore migrate to the positive (red) pole.
