Homework Help: Biology

Posted by Lilah on Wednesday, January 28, 2009 at 10:57pm.

Two samples of DNA have the same melting point and density. Does this prove that they are from the same species? Explain clearly and back up your reasons.

I read in my notes and all it said was that DNA species isolated from different organisms have different melting temperatures. But I don't know if every single species have a different Tm? Also I coulnd't find anything about density.

Thanks!
