Transcript: Forensic DNA Analysis
Dr. Camilla Speller: I would define DNA as the blueprint for our bodies, sort of an instruction manual that contains all the genetic information. DNA analysis is actually very reliable and is probably the most accurate personal identification system that we have. It ranks right up there with fingerprinting.
We find DNA in every cell in our body. The majority of our DNA is nuclear DNA and these are our twenty-three chromosomes. DNA can be used to identify different people. It can be used to tell us about the sex of a person if it's unknown. It can be used to tell us about any genetic disorders and it can be used to infer who our parents are or for paternity tests, who we're related to.
In forensic DNA a match usually implies that you have a personal identification. In this case it would mean that based on your DNA finger-printing, you are able to secure a personal identification for those remains.
