Textbook Question
Chapter 11, Problem 7PDQ
In Kornberg’s initial experiments, it was rumored that he grew E. coli in Anheuser-Busch beer vats. (Kornberg was working at Washington University in St. Louis.) Why do you think this might have been helpful to the experiment?

You have discovered a new species of archaea from a hot spring in Yellowstone National Park. After growing a pure culture of this organism, what strategy might you employ to sequence its genome?
In the Meselson experiment, would it have been possible to utilize N14 in the original bacteria and only allow growing bacteria to access N15 to build new (F1) bacteria and get the same results? Explain why. (I need an answer in full complete sentences with the question restated in the response.)

These phages were used to infect E. coli cells and the cells were further centrifuged to form pellets. Why was the radioactivity level of S-32 found greater outside the cells compared to the E. coli cell pellets? Explain briefly. If the experiment is repeated in the same manner but this time the phage protein coats are labelled with isotope X and the phage DNA with isotope Y, which isotope’s radioactivity will be found in greater amounts in the E. coli cell pellets after centrifugation?
