Avery and his group used enzymes to degrade DNA, RNA and protein in 3S bacteria. DNA from those cells was then tested to see if it can convert 3R cells into 3S cells. It was observed that 3R cells were converted to 3S cells except when the DNA was destroyed. Thus, DNA was pin-pointed as the transforming agent.
