WitrynaÒ. . . Al Hershey had sent me a long letter summarizing the recently completed experiments by which he and Martha Chase established that a key feature of the infection of a bacterium by a phage was the injection of the viral DNA into the host bacterium. Their experiment was thus a powerful new proof that DNA is the primary … WitrynaHershey and Chase used T2 phage, a bacteriophage. The phage infects a bacterium by attaching to it and injecting its genetic material into it. They labeled the phage DNA with radioactive Phosphorus -32. They then followed the phages while they infected E. coli.
WitrynaIn the Hershey and Chase experiment, radioactively-labeled. A) 32P did not enter the cell. B) 32P remained inside the cells after vigorous shaking. C) 32P was removed from the cells by vigorous shaking. D) 32P and 35S remained inside the cells after vigorous shaking. E) 32P and 35S were removed from the cells after vigorous shaking. WitrynaThe protein shell of the virus was tagged with radioactive sulphur, and this ended up in the supernatant. The heavier bacterial cells formed the pellet, so Hershey and Chase …

WitrynaThe Hershey-Chase experiment proved DNA is genetic material by using the isotopic marker ³²P, which labels DNA. They infected a bacterium where it replicated the ³²P as genetic material demonstrating DNA is genetic material.. DNA was first isolated from white blood cells by Friedrich Miescher, who called it nuclein because it was isolated …
WitrynaThe Hershey and Chase Experiments In 1952 (7 years after Avery's demonstration that genes were DNA), two geneticists: A. D. Hershey and Martha Chase provided further proof.
