  • $\begingroup$ VTC because this question is identical to the later one, and the later one is better asked and has better answers. $\endgroup$ – March Ho Jun 8 '15 at 4:41

From the comment section:

Mostly segregation of PCR-amplified DNA from non-amplified DNA. Typically no DNA or sample should ever enter a specific room designed to prepare the MasterMix for PCR (this is true for diagnostic labs, in the research one I never saw that). For the rest, following good laboratory practices (google that) should be enough.
