Jurassic Park?

How long does DNA last? Nearly all your cells contain DNA, and there may be traces in your body long after your death. Short fragments of DNA may last for 50,000 to 100,000 years before water, air and microbes finally destroy them. Eventually, even the DNA in insects trapped in amber decays, and is lost forever - so ideas from the movie Jurassic Park are, and always will be, just fiction.
