DNA evidence has been the most bulletproof evidence for forensic sciences in recent years. Not anymore. A laboratory at Nucleix, a life-sciences company, has demonstrated it is possible to manufacture DNA that would be accurate enough to pass forensic scrutiny:
“You can just engineer a crime scene,” Nucleix founder Dan Frumkin told The New York Times. “The current forensic procedure fails to distinguish between such samples of blood, saliva, and touched surfaces with artificial DNA, and corresponding samples with in vivo generated (natural) DNA.”
“Any biology undergraduate could perform this.”
Frumkin and co-authors announced their technological achievement in a paper for the journal Forensic Science International: Genetics. Fortunately, the company also offers a solution: one particular methyl group appears in naturally-occuring DNA, but not in Nucleix’s product.
