WebDNA fragments are injected into wells and an electric current is applied along the gel. DNA is negatively charged so it is attracted to the positive end of the gel. The shorter DNA fragments move faster than the longer fragments. We will use E-Gels here at the high school, which are very simple. WebDNA Fingerprinting After the DNA has been digested with one or more restriction enzymes, it is separated by size using gel electrophoresis. A radioactive probe is then used to identify certain fragments of DNA that may differ between individuals.
