Answer:
In 1944, Avery, McCarty and MacLeod dicovered that protein-digesting enzymes (proteases)and RNA -digesting enzymes (RNases) did not affect transformation, so the transforming substance was not a portein or RNA. Digestion with DNase did inhibit transformation. They concluded that DNA is the hereditary material.
