The experimental findings of the Avery–MacLeod–McCarty experiment were quickly confirmed, and extended to other hereditary characteristics besides polysaccharide capsules. However, there was considerable reluctance to accept the conclusion that DNA was the genetic material. According to Phoebus Levene's influential "tetranucleotide hypothesis", DNA consisted of repeating units of the four nucleotide bases and had little biological specificity. DNA was therefo… WebAvery’s Transform Experience In the 1930s and 1940s, American biologist Oswald T. Avery, along with his colleagues Colin M.
