It must be able to replicated accurately. Oswald Avery, Colin MacLeod and Maclyn McCarty took up where Griffith's experiment left off and began purifying DNA from the other components of the virulent bacteria. Their discovery revised the concept of protein as genetic material to DNA as genetic material. By extracting the water-soluble materials from bacteria and precipitating DNA using chloroform, Avery acquired a purified sample of DNA that he could use to transform bacteria. Griffith was a British medical officer and geneticist. Avery, Oswald T. (b.Halifax, Nova Scotia, Canada, 21 October 1877; d.Nashville, Tennessee, 20 February 1955) biology..
