Frederick griffith discovery on dna
WebFrederick Griffith In 1928 an army medical officer named Frederick Griffith was trying to find a vaccine against streptococcus pneumoniae , but instead made a breakthrough in world of heredity. He did four experiments in which he injected strands of bacteria into mice, one strand that was harmless (R) and one that was harmful (S). WebIn 1928, Frederick Griffith was able to transform harmless bacteria into virulent pathogens with an extract that Oswald Avery proved, in 1944, to be DNA. In 1952, Martha Chase and Alfred Hershey used radioactively labeled virus DNA to infect bacteria, proving the same point. These important experiments established that DNA is the genetic material.
