Our perception is a stimulus response NOT caused our genes. It is caused by awareness of our environment by a specific receptor that triggers a physical response by a specific effector.
Perception controls behavior.
The behavior of our cells is NOT programed. Our behavior is continually responding to our perception of our environment.
ROLE OF DNA: Blueprint for how to make proteins. Genes DO NOT self activate. Genes CAN NOT turn themselves on or off. There is no such thing as a cancer gene. If there were cancer genes you would get cancer before you were born as soon as your cells would start dividing.
