DNA samples from a decomposed bodies (just bones)

Post by bradmoss » Wed Jan 04, 2006 6:59 pm

I have been always puzzled when reading in the news the police is going to dig out a corpse to take DNA samples, sometimes bodies buried several years ago.

How can they take DNA samples from a decomposed body (just bones), how is that the DNA they take isn’t decomposed, where they take the DNA from?

I would appreciate very much your help understanding this.

Hmm... I'm guessing DNA is preserved because osteocytes(bone cells) are inside some small holes in the bone, named osteoplasts. Just a guess

What i could never understand is how the heck someone can obtain DNA from a fossil..
