I read an article a while ago about a lab experiment on mice who were put into a sterile environment where all the trillions of microbes and bacteria that exist on and in a physical body were not permitted to grow. This had an interesting effect in that the mice grew all deformed. I was led to believe that the DNA was responsible for how a body is formed and shaped with all it's individual traits. There must be some connection between the two (DNA and microbes/bacteria). Maybe the microbes work for the DNA. This is what I intuited, not sure if it's correct or not. Any thoughts on the matter?
