    Here are some links:

    Wiley InterScience :: Session Cookies

    SpringerLink - Journal Article

    http://arxiv.org/ftp/physics/papers/0703/0703074.pdf

    Of course, if you get it hot enough, it unravels and decomposes -- and if the biological host is alive, he won't be for long.

    DNA is composed of nitrogenous bases each combined together with hydrogen bond and it's easy to broken by heat so when the temprature increase this bond broken and two strands separated after temprature return to be normal the two strands combine together and forming the helix of DNA.
    DNA is not a protein.
