Avery, McCarty & MacLeod
{"Image DocumentName": "Avery, McCarty & MacLeod", "Image ImageDescription": "1944 | ??!! Avery, McCarty & MacLeod. Conclusion. first experimental evidence that DNA was the genetic material. Maclyn McCarty (June 9, 1911 \u2013 January 2, 2005) was an American geneticist. Oswald Avery (October 21, 1877\u20132 February 1955) was a Canadian-born American physician and medical researcher. Colin Munro MacLeod (January 28, 1909 \u2014 February 11, 1972) was a Canadian-American geneticist. After Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty published the 1944 article, a number of their contemporaries immediately understood that transformation was the transfer of genetic material from one bacterium to another, and that the transforming substance, DNA, must be the genetic material. However, the team s somewhat tentatively stated conclusions were not met with complete acceptance. At the time, the belief that DNA was a monotonous chain of four repeating nucleotides--structurally important but of little physiological interest--was still difficult to overcome. The belief that only proteins possessed the structural complexity necessary to carry hereditary information was pervasive among geneticists. Many of the scientists who had previously thought that genetic material was protein still believed that the effects of the transforming principle were perhaps due to some undetected protein associated with the DNA.
