What Can We Do About Antibiotic-resistant Bacteria?
Summarize, evaluate, and argue the validity of the data that demonstrate the problem of antibiotic-resistant bacteria. Then present a plan for reducing this problem in the future. Keep these questions in mind:
• What data supports the hypothesis that antibiotic-resistance is on the rise? What problems do you see in this data? Can you propose a way to overcome these problems?
• Which methods have been successful in decreasing the number of antibiotic-resistant bacterial strains? Which methods have not?
• What shortcomings or errors do these given studies have? Can you design a new study that would overcome them?Student Deliverable:

Suppose that you are working with Drosophila and are studying genes, a, b, c, d, e, and f that are all linked in a region on a chromosome, but their order is unknown.
Chemical analysis of the DNA of a virus from Mars reveals that ithas 48% G, 48% C and 4% A. Suggest some possible structures for this DNA?
Shared derived characters are ___.
A cross is made between two E. coli strains: (Hfr arg+?bio+?leu+) x (F? arg??bio??leu?). Interrupted-mating studies show that arg+ enters the recipient last, so arg+ recombinants are selected on a medium containing biotin and leucine only.
Provide two examples where the nature of the DNA sequence itself is the basis for an increased rate of mutation. Explain why these sequences predispose to mutations.
Why is the hydroxyl functional group of carnitine used when it is combined with a fatty acid and could any other functional group, in theory, be used?
Why is it more important to use fresh cultures in the Coagulase test than in a test medium such as milk agar?
