- TRY TO KEEP IN SHORT AND USE OWN WORD FOR THIS QUESTION 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?arrow_forwardTransfection efficiency refers to a) total number of transfected cells per dish O b) total number of transfected cells per field of view total amount of plasmid DNA added per sample d) number of cells per 100 that have taken up plasmid DNAarrow_forward1.

In one case it is a plasmid that is transferred via conjugation, in the other case it is a part of the bacterial chromosome that is transferred via transformation. In which of the two cases is it most likely that the transferred DNA will remain and be able to function in the recipient cells? Explain the biological background to your answer . How do I break down the question so I answer it fullyarrow_forwardYou are attempting to propagate bacteriophage of Bacillus cereus using a liquid batch culture. A growing culture of B. cereus is inoculated with your bacteriophage. The day before you tested the bacteria and the phage batch and they both behaved as expected. You made sure that all containers are labeled appropriately. Immediately after inoculation, you take a sample but are unable to detect any bacteriophage in the media. What is the most likely explanation? O You used the wrong bacteria or the wrong bacteriophage. There is an issue with the phage batch. O There is a problem with your bacterial culture of B. cereus. O It is too soon. The bacteriophages are still replicating and assembling inside the bacterial cells and are therefore not detectable in the growth media.arrow_forward
- In August 2021, there was a multi-state outbreak of melioidosis, an infectious disease caused by the bacterium Burkholderia pseudomallei, thought to arise from imported products. Burkholderia pseudomallei can be grown in culture. In terms of human health, why might it be critical to grow a pure culture of bacteria?arrow_forwardYou have isolated a strain of E.coli that is resistant to penicillin,streptomycin,chloramphenicol and tetracycline. You also observe that when you mix this strain with a strain that is sensitive to all four antibiotics, the new strain becomes resistant to streptomycin,penicillin and chloramphenicol but not tetracycline. Explain how this is so?arrow_forwardBacillus thuringiensis makes toxins that kill insects. These toxins must be applied several times during the growth season to prevent insect damage. As an alternative to repeated applications, one strategy is to apply bacteria directly to leaves.However,B. thuringiensis does not survive very long in thefield. Other bacteria, such as Pseudomonas syringae, do survive.Propose a way to alter P. syringae so it could be used as an insecticide.Discuss advantages and disadvantages of this approach compared with the repeated applications of the toxins from B. thuringiensis.arrow_forward
