How long can DNA last ?

Like many things, it depends on how you store it. Like many biological things, major enemies are oxygen, water, and photons with certain energies (say, UV for example). If you keep it dehydrated and in the dark, it should last for a very, very, very long time. Cold is also wonderfully good; as a cheat, at absolute zero (-298˚C) everything last forever by definition (if I understand correctly).
This is why it’s fun to think about what might happen to DNA in amber[that was the original Jurassic Park idea]; it’s out of the air & water there.
