WitrynaWe then designed an experiment to test which component entered the bacteria for infection. In two parallel experiments, we combined the radiolabeled phage with bacteria that were not labeled. We waited long enough for the phages to attach, and then disrupted the attachment by mixing the culture in a Waring blender.

Chase's Experiment (Blender Experiment): heat-killed S-bacteria responsible for the transformation of R-bacteria ii) This experiment is known as the blender experiment because a kitchen waring blender was used as a major piece of apparatus (Fig.1.3). WitrynaThe Hershey and Chase experiments used bacteriophages, or viruses capable of infecting bacteria, in order to determine whether genes were made of proteins or DNA. Hershey and Chase labeled the protein coats of one set of bacteriophages with sulfur and the DNA of a second set with phosphorus.

Hershey won the Nobel Prize in Physiology/Medicine in 1969, along with Salvador Luria and Max Delbrück, for discovering in 1940 that when two different viruses infect the same bacterium, they sometimes exchange genetic information. primary medical associates auburn alabamaWitrynaHershey and Chase used radioisotopes P-32 and S-35 to label the different phage components. P-32 labels DNA, and S-35 labels protein. (DNA contains phosphorous, but not sulfur; proteins contain sulfur, but not phosphorous). They then grew E.coli in the presence of either P-32 or S-35 and then infected them with T2 phages. primary medical care at the crossroadsWitrynaChase left Hershey’s lab in 1953 and their collaboration ended.
