When the Oxford team of Ernst Chain and Nor- man Heatley had laboriously collected their first two grams of penicillin (probably no more than 2% pure!), Chain injected two normal mice with 1 g each of this preparation, and waited to see what would happen. The mice survived with no apparent ill effects. Their boss, Howard Florey, was furious at what he saw as a waste of good antibiotic. Why was this experiment important?
What is transformation? Describe Grifith’s experiment to show transformation? What did he prove from his experiment?
In detail explain the experiment that helped Hershey and Chase recognize DNA as a genetic material

- One experiment that showed the DNA carried genetic information was the "Transformation" experiment by Avery, McCarty, and MacLeod where they injected mice with non-pathogenetic bacteria that had been incubated in the remains of pathogenic bacteria. What did they find when they incubated non-pathogenic bacteria in just the protein from the pathogenic bacteria?
