studied 2 strains of bacteria that cause pnumonia. he found that one strain could be changed into the other form. text book

found a molecule that transformed the R strain of bactria into the S strain. Avery isolated different macromolecules like DNA, proteins, and lipids from killed S cells. Avery concluded that when the S cells were killed, DNA was realsed. text book

Published results of experiments that provided definite proof that DNA is a transforming factor. these expiriments involved bacteriophage whcich attacks bacteria. they used a tecnique called radioactive labeling to trace the fate of DNA and protein as the bacteriophages infected bacteria and reproduce.

His reachearch went towards X-ray diffraction, and to the development of radar. He is best known for his work at King's College London on the structure of DNA. In recognition of this work, he, Francis Crick and James Watson were awarded the 1962 Nobel Prize for Physiology or Medicine, "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material. wikipedia
