Faking DNA Evidence: You Can Do That?

Fake DNA


An Israeli company has created blood and saliva samples that contain fake DNA evidence, and the modification is undetectable in standard lab tests, reports Technology Review. Tel Aviv-based Nucleix demonstrated that it can replicate DNA from samples or produce new DNA based on a person’s genome sequence. The phony DNA goes into donor blood or saliva, scientific magic happens, and voila: fake crime scene evidence.


The company, conveniently, also has designed a proprietary test to distinguish between naturally shed DNA and its counterfeit cousin. All the same, this very falsified-evidence scenario has been “cited as a concern for those who make their genome sequence public,” Technology Review notes. It’ll be a concern for those who don’t choose to make their DNA public, too:  Just this spring, the FBI expanded its collection of DNA to include people awaiting trial (who may well be acquitted) as well as detained immigrants.
