What Are Practical Applications of Gel Electrophoresis?

Gel electrophoresis allows scientists to separate strands of DNA--allowing for easier identification and examination of its components. As the DNA moves through the gel, it helps separate the larger and smaller sections from each other. This process offers several beneficial applications of providing genetic information.

Illness

• Gel electrophoresis can help scientists identify damaged genes, including oncogenes. It can also help identify certain genetic diseases such as sickle cell anemia, Huntington’s disease and Duchenne muscular dystrophy, according to the State University of New York. Gel electrophoresis can also identify viruses.

Family

• Gel electrophoresis can determine paternity as well as establish genetic links between larger groups of people, according to Colorado University.

Animals

• Gel electrophoresis offers many benefits in fields dealing with animals. Zoos can use this technique to reduce the negative impact of inbreeding. Taxonomists and evolutionary biologists can learn more about evolutionary relationships, identify species and document differences between them. Those studying animal behavior can use DNA to glean information about kinship of animals and how it impacts interaction with other animals.

Crime

• Scientists can also use this procedure to examine tissue samples found at crime scenes.
