> Hi,
> Does autoclaving (121C for 20mins) DNA destroy it? What I mean by "destroy" is to break the covalent bonds between adjacent nucleotides and NOT the breaking of ionic bonds between the two strands. I argue that 121C is well above the melting temperature of DNA (95C), which should do the trick.

No. Although it break a lot of it into fragments <100mers. The melting 
temp refers ot the inter-strand bonds so is not relevant.
