Re: Dinosaur Protein
And, why does DNA not hold up so well?
It's a very long and fragile polymer that needs to be constantly repaired in
living creatures. It was once thought that *Deinococcus radiodurans*
bacteria are immune to even huge doses of radiation by somehow shielding
their DNA from damage. It turns out that they're just really good at fixing
the damage (instead of avoiding it).
Once an organism is dead, the mechanisms by which DNA is repaired cease to
function, and the molecules quickly begin to fragment.
