After the phage was attached to the bacterium, the radioactive element was found in the phage, but not in the bacterium. This means that the phage's proteins stayed on the outside of the bacterium.

WitrynaFor their experiment, they used the bacteriophage T2. A bacteriophage is a virus that only infects bacteria. This particular virus infects Escherichia coli. T2 had a simple structure that consisted of just 2 components – an outer protein casing and the inner DNA. Hershey and Chase took 2 different samples of T2. They grew one 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..
