Consider the phase variation of flagella in Salmonella. Describe the phenotype of a cell in which hin is deleted. Will it be motile? Will it undergo phase variation? Which flagellin(s) will be used, if any? Name two bacterial defenses against bacteriophages and explain how they work How might a phage evolve resistance to the CRISPR host defense?
Penicillin was first used in the 1940s to treat gonorrhea infections produced by the bacterium Neisseria gonorrhoeae. In 1984, according to the CDC, fewer than 1% of gonorrhea infections were caused by penicillin-resistant N. gonorrhoeae. By 1990, more than 10% of cases were penicillin resistant and a few years later the level of resistance was 95%.
Explain the various ways this resistance could be spread among the cells. Could this resistance pass to other infectious bacteria from N. gonorrhoeae?
Which of the statements is TRUE about conjugation?
a)
Plasmid DNA is transferred from a donor (F+) cell
b)
It may only be performed by competent cells
c)
DNA is always integrated into recipient chromosome
d)
It may be specialized or generalized

- What part of the A. tumefaciens DNA gets transferred to the genome of a plant cell during infection?arrow_forwardBriefly discuss the following questions in 3 to 5 sentences. What is horizontal gene transfer? What are the three mechanisms for this to occur in bacteria? What are the components needed for the processes of transformation, conjugation, and transduction? How does each process occur? What genes are involved in each process? How do generalized and specialized transduction differ? What is the end result of each? What is recombination? What is the importance to bacteria & archaea? What are the two types of recombination? What are the details of each type? What components are needed for each type?arrow_forwardBacterial conjugation has medical consequences. For example, certain plasmids contain genes that code for toxins. The causative agent of a deadly form of food poisoning, E. coli 0157, synthesizes a toxin that causes massive bloody diarrhea and kidney failure. This toxin is now believed to have originated in Shigella, another bacterium that causes dysentery. Similarly, the growing problem of antibiotic resistance is partly attributable to the spread of antibioticresistant genes among bacterial populations. Antibiotic resistance develops because antibiotics are overused in medical practice and in livestock feeds. Suggest a mechanism by which this extensive use promotes antibiotic resistance.arrow_forward
