I recently had a discussion with a statistician in my school about memory. Among other things, he told me that it has been experimentally demonstrated that when one extracts DNA from any organism and then induces a stressful condition on that organism, the same effects on DNA can be observed both in that organism and the DNA sample that was extracted before the stressful condition. From what I could tell it is as if he was suggesting that DNA has some kind of a telepathic property that enables this phenomenon.
Now, I am not a biologist (and neither was he) but I am heavily suspicious of this idea. Also, when I asked him for a specific paper on that, he simply told me that there are many and that it is fairly easy to find them. However, my efforts to find anything on google scholar were fruitless so far.
So I want to know: Is such a thing possible and have there been any experimental studies on that?
