Background
DNA gel electrophoresis is a technique for separating and recognizing DNA fragments according to the size of DNA molecules. DNA fragments of different sizes were loaded onto a porous gel made of agarose (agarose is a carbohydrate found in red algae). After application of an electric field, the fragments will move in the gel due to the negatively charged phosphate groups on the DNA. Smaller DNA fragments will migrate through the gel relatively easily and larger DNA fragments will migrate more difficultly than larger fragments.
