Describe it and explain how you would interpret the results.
- Briefly describe the Kirby-Bauer test and its purpose.In the Hershey–Chase experiment, the radioactive label 32P was present inside bacterial cells (i.e., in the pellet), whereas the radioactive label 35S waspresent outside bacterial cells (in the supernatant). What would the researchers have concluded had the reverse been true, that is, if the radioactive label 35S were inside the cells and the radioactive label 32P were outside the cells?If the 1-mL sample had been added to 99 mL of diluent to make the first dilution (instead of 9 mL), how many cells would be in that particular dilution?
