WitrynaPrerequisites. Hershey-Chase experiment focussed on the infection of bacteria with the bacteriophage T2. Bacteriophages, often called phages, are viruses that infect bacteria to maintain their life cycle. Crucially for this experiment, phages consist of only two materials: a protein shell outside and DNA inside. WitrynaHershey and Chase wanted to check if it was the DNA or the protein of the bacteriophage that was injected as genetic material into the bacterial cells. For this, they cultured bacteriophage in two different media - one containing radioactive sulphur 35 S ... Question Papers. Install app ... umhb national championship
