Did you know … DNA can be fingerprinted, too?

Finger printing is the record of someone’s finger print. DNA fingerprint is a test to identify and evaluate the DNA of a person's cells.

DNA fingerprinting involves isolating and extracting DNA from cells, amplifying it through PCR, and running it through gel electrophoresis. Restriction enzymes are used to cut the DNA into fragments of different sizes that are called short tandem repeats [STRs].  STRs are different for everyone.

Studies have shown that DNA evidence is 99% accurate, making it one of the most foolproof pieces of evidence you can possibly use in court. Like fingerprints, no two people have the same DNA. If a mistake occurs, it's typically because of human error.
