Not being a CSI but I think common bleach (which is alkaline) will destroy dna in blood.

i'm not very well versed in biology, or chemistry, but as I understand it, dna stands for deoxyribonucleic acid, so wouldn't you need a base in order to neutralize it? bleach, maybe?

Just what kind of crime are you trying to destroy evidence of?
-
DNA is microscopic and doesn't in itself need any getting rid of. You might have a need to get rid of hair, bone, saliva, blood or semen, all of which can contain identifiable DNA, and that may be innocent, or not!

Hydrofloric acid, hydrocloric acid, muriatic acid ... any sufficiently volitale acid will do. Just be warned, though ... any acid sufficient to obliterate DNA is also sufficient to severely burn skin!

I could tell you - but then I'd probably get done for being an accessory.....or trying to pervert the course of justice....

You're better off just buying a new keyboard. They're pretty cheap these days.

You can definitely get rid of DNA because there are enzymes which the body makes and are found in the environment called DNAase enzymes. This means that they literally eat DNA and cut it up. So you can definitely get rid of DNA. Leaving DNA in the sun can also break it down. Changing DNA is actually very different. Changing happens in all of us due to a process called mutation, in which your DNA accidentally swaps a few of the DNA letters around. These letter swaps usually get fixed by DNA repair machinery within the cell. If it's not, it can sometimes lead to cancer. However, there's not actually a technique in which you can physically change DNA, say, at a crime scene, to implicate somebody. The best way to do that is to literally sprinkle some of their DNA at the scene.
