Dr Lipton [See his videos on thios topic: Video #1 Video #2] says our environment feeds signals to our senses which feeds signals to our brains which filter these systems via our beliefs. The brain then sends signals to all cells which react to them causing certain genes to be activated. This activation creates RNA which encodes for a particular protein. The protein then can start the process over by signaling other cells. Dr Lipton can take a cell in a Petri Dish and remove its DNA. The cell continues to live and function. This proves our DNA is not what predetermines our cells actions but our environment does.
