my removal of your content on DNA melting 

I removed the content you placed when creating the article because it was wrong and unreferenced. Mutations do not have "weird structures"  a point mutation might start with a single nucleotide mismatch, but those are rapidly detected and repaired to form a stable bonded double-helix structure, and subsequent rounds of DNA replication match each base with its complement. Perhaps your wording was wrong, perhaps you were thinking of an obscure related technology that I have heard of, but you didn't give a reference and I'm not going to help you with this, because you're being rude. I find it disturbing that you apparently made this scientific page on wikipedia claiming a statement of fact that was in merely based on your own speculations.
