Another problem has been that ancient DNA in bone, the usual source, is heavily contaminated with bacterial DNA. Schuster has found that hair is a much purer source of the host's DNA, with the keratin serving to seal it in and largely exclude bacteria. A third issue is that the DNA of living cells can be modified, but only very laboriously and usually at one site at a time. (International Herald Tribune)
