- Bacterial transformation is a major concern in many medical settings. Why might health care providers be concerned? Pathogenic bacteria could introduce disease-causing genes in non-pathogenic bacteria Antibiotic resistance genes could be introduced to new bacteria to create “superbugs. ” Bacteriophages could spread DNA encoding toxins to new bacteria All of the above.arrow_forwardBacterial transformation involves DNA transfer to a recipient cell Group of answer choices as naked DNA in solution by a bacteriophage by cell-to-cell contact by sexual reproductionarrow_forwardIn a petri dish with solidified agar with escherichia coli, enterobacter aerogenes and staphylococcus aureus, you streak a loopfull of lytic T4-phage in a single line onto the center of the the dish, how do you know if bacteriophage infected the bacteria. why didn't the bacteriophage infect all 3 bacteria?arrow_forward

What cellular components must be copied before a cell splits in two? Why is this difference in replication rate an important part of our vulnerability to bacterial pathogens?arrow_forwardSome bacteria may have higher mutation rates than others following exposure to UV light. Discuss a reason why this might be the case. What experiments could you do to determine whether this is a likely possibility?arrow_forward
- In Figure 6-13, explain at the protein level why this heterokaryon can grow on minimal mediumarrow_forwardComplete the following statement about conjugation. Bacterial confirmation is the equivalent of sexual reproduction in eukaryotes in that it necessitates cell to cell contact. The donor cell just contain a 1. Blank which is distinct from the larger bacterial chromosome. The 2. Blank carry genes in the 3. Blank which regular the conjugation processarrow_forwardYou 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_forward
