What is the effect of temperature on DNA?

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.

Thanks again Perito =]

since DNA is a protein it can be denatured if the temperature is too high....

DNA is not a protein but can be denatured by heat. Is is a suger attached to a base and phosphate(s)

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.
