DNA fingerprinting is
a way of getting a person’s identification. This type of method had been
used since the mid 1980’s. It was used first to discover genetic diseases
but now is also used to help catch criminals. It is now used in forensic science,
maternity tests and personal identification. DNA fingerprinting allows a scientist
or any qualified worker to match the DNA of any person. All the worker needs
is a sample of DNA from hair, nails, blood, skin or even saliva. If the DNA they
found matches the sample they received then they most likely have the right specimen's DNA.
