In the experiment by Bernard Davis, bacterial F+cells and F- cells were growing while separated by a filter. Filter pores allowed the passage of the liquid medium but not the bacteria cells. As a result: 1) prototype colonies grew well on minimal medium 2) F+ cells were converted to F- cells despite the physical separation 3)F- cells were converted F+ cells despite the physical separation 4)F+ cells were not converted to F- cells because of the physical separation 5) F- cells were not converted to F+ cells because of the physical separation 6)there was no growth of prototypes on minimal medium

If you were to analyze three separate colonies from the plate above, would you expect them all to be the same species of bacteria? Why or why not?
You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?

Engineered bacteria are commonly used and cultured in pharmaceutical laboratories to produced drugs like insulin. However, during one instance, with the desire to increase the rate of insulin production, one scientist tried to modify the process and put another substance (chemical x) in the growth medium which is chemically almost the same to the substance (chemical x’) normally put in the medium. After which, the scientist found out that the amount of insulin produced in the medium decreases as compared to the normal production. Again, within the context of our discussion, explain the possible reason for the observed result.
