who demonstrated that dna is the genetic material
In 1952, the research team of Hershey and Chase published a report that concluded that DNA is the genetic material of the bacteriophage (a virus that infects bacteria) T2 (strange name!). They knew that when a bacteria was infected with this phage, the bacteria soon became a machine that produced new phages.n the other hand, if DNA were the genetic material, the opposite would be true. In their experiments, Avery et al. found that protease did not affect the ability of 'dead' S to transform R but DNAase did, therefore they concluded that the genetic material in transformation is most likely DNA.
