Solution
RNase is a hydrolytic enzyme that specifically degrades ribonucleic acid (RNA). In Tube 2, RNase was added to the purified extract to destroy all RNA present. Since transformation still occurred after RNase treatment, this indicated that RNA was not the genetic material responsible for transformation.
