WebWhich of the following provides clues that your gel electrophoresis is running properly (choose all that apply) A) Bubbles rise from the electrodes. B) You can see the loading … 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.
