Agarose Gel Electrophoresis of different dye mixtures illustrate how things of different electrical charge and size can be separated when applying an electric field and utilizing a molecular sieve (agarose).
We simulate DNA fingerprinting in the lab using a technology referred to as Restriction Fragment Length Polymorphism. A more sensitive and current method of DNA fingerprinting utilizes the Polymerase Chain Reaction (PCR) to amplify specific sequences of DNA.
Watch the video below for further elaboration on how this works.
