1944, Hershey and Chase Another major experiment was performed by Hershey and Chase in 1944. This experiment has come to be known as the Blender Experiment because a kitchen blender was used in the protocol. The blender experiment utilized the bacteriophage T2 of E. coli . One of the "T-even" phage, the T2 phage is a complex phage which contains a genome of ds DNA. All viruses must contain a genome + a protein capsid . The T2 phage is a complex phage and also contains a tail sheath , base plate and tail fibers . The capsid, sheath, base plate and tail fibers are all composed of protein. At the time of Hershey and Chase it had not been definitively demonstrated that DNA was the genetic information. They designed the following experiment to prove that DNA was the genetic information for the T2 phage: First the proteins of the phage were labeled with 35S-methionine/cysteine. The 35S radioisotope of Sulfur was incorporated into the methionine and cysteines of newly synthesized phage proteins. The phage proteins were the only molecules labeled.
