DNA or faux DNA?

A laboratory at Nucleix, a life-sciences company, was able 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,” Frumkin and co-authors wrote in a recent Forensic Science International: Genetics study that announced the technological achievement.

Fortunately, the company offers a solution: one particular methyl group appears in naturally-occuring DNA, but not in Nucleix’s product.
