DNA electrophoreses was developed in 1984 by Dr. Alex Jeffreys. The use of DNA electrophoresis quickly became a way to convict criminals of crimes. DNA electrophoresis has also helped identify genetic diseases markers as well as the identification of the remains of humans. (DNA Fingerprinting - ID of DNA Restriction Fragmentation Patterns).
In order to create a DNA fingerprint, a sample of cells containing DNA must be obtained first. This may be in the form of hair, blood, or skin. DNA is extracted and purified from the cells. This was originally done with restriction fragment length polymorphic technology. During this procedure, DNA is broken down into individual strands at specific locations. These strands, known as restriction enzymes,
