The tests on the purified substance produced data that supported the idea that DNA is responsible for transformation. One observation was that when the substance was treated with an enzyme that breaks down DNA, it lost its ability to transform. This suggested that DNA was necessary for transformation. Another observation was that the substance could transfer genetic material to bacteria and change their characteristics. The substance also had properties similar to DNA. All of this data supported the hypothesis that DNA is the transforming factor.
