Astronaut conducting an electrophoresis experiment aboard the space shuttle Columbia. Two-dimensional gel electrophoresis In DNA fingerprinting, fragments of DNA are separated on a gel using a technique called electrophoresis. This creates a pattern that can be analyzed and that is unique to each individual, with the exception of identical twins. In gel electrophoresis an electric field is applied to a buffer solution covering an agarose gel, which has slots at one end containing DNA samples. The negatively charged DNA molecules travel through the gel toward a positive electrode and are separated based on size as they advance.
