Watson and Crick are known for the double helical model of DNA that they constructed. Griffith’s transformation experiments revealed that a “transforming principle” from heat-killed S strain of pneumococcal bacteria could transform the R strain into the live S strain. Avery, MacLeod and McCarty figured out that DNA was in fact the “transforming principle”. Hershey and Chase, through a cleverly developed experiment, re-confirmed that DNA and not protein, is the genetic material in most organisms.
