DNA FINGER PRINTING

• DNA finger printing (DNA profiling, DNA testing) is a process which uses fragments of DNA to identify the unique genetic makeup of an individual.
• Before the invention of PCR, the only method of establishing and authenticating personal identification was by the DNA fingerprint process.
• Since no two individuals have been found to have identical pattern of ridges on their fingers, this method has been universally accepted as a means of personal identification.
• In 1984, Sir Alec Jeffreys at the University of Leicester in England was able to distinguish differences among individuals based solely on their DNA composition.
