This sort of reminds me of the Silo series of books by Hugh Howey. If you have not read the books and like scifi ... obligatory spoiler alert... One of the themes in the book is the impending terrorist doom that could unfold by using nanotechnology to target certain demographics (ie genocide). I think nanobots reading human DNA would be fairly hard but nanobots recognizing biomemes might not be. That is using biomemes might be easier than DNA fingerprinting for nanobots. I could be completely wrong on my assumptions not to mention I have no background in bio or nano tech.
