Summary Introduction
To review:
The type of transduction mediated by a phage isolated for Salmonella enterica.
Introduction:
Transduction is a process in which a bacteriophage carries the host DNA (deoxyribonucleic acid) from one cell to another. It is of two types, generalized transduction and specialized transduction. Generalized transduction is a process in which the phage can take any gene from the donor and transfer it into the recipient. Specialized transduction is a process that can only transfer some closely linked genes.

One of the reasons why phage therapy has not been applied widely is that bacteria can become resistant to bacteriophages as well, through mutations in genes encoding for specific proteins. What would be a protein in the bacterial cell that, if mutated, would make that cell resistant to phage infection?
Which of the following statements regarding transduction is FALSE?
A) transduction reduces genetic variation within bacterial populations
B) the inadvertent packaging of bacterial DNA into a phage particle can lead to generalized transduction
C) specialized transduction can only be facilitated by a phage capable of integration into the bacterial genome
D) generalized transduction involves the transfer of DNA that is exclusively bacterial
E) specialized transduction must be preceded by viral integration and imperfect excision
F) specialized transduction involves the transfer of both bacterial and viral DNA
Scientists at the SEA Phages lab were asked to find a phage that might infect a strain of M. abscessus that is infecting a young patient. Because the scientists did not have any phages known to infect M. abscessus, they first tested M. smeg phages that are also known to infect M. tuberculosis to
see if they could infect this specific strain of M. abscessus. Why did they start with those phages? Select the best answer.
O Phages that infect M. tuberculosis will also infect M. abscessus
O The phages have already been FDA approved for use in phage therapy
O Phages that infect two different hosts have a broader host range and are more likely to be able to infect a third host (such as M. abcessus)
O The phages are lytic, which makes them good candidates for phage therapy
O More information is known about the genomes of these phages than other phages

- The size of a DNA fragment that can be inserted into an unmodified λ vector is very limited. Large segment in the central region of the λ DNA molecule can be removed without affecting the ability of the phage to infect Escherichia coli cells. However, the deletion of this non- essential region does affect the life cycle of the bacteriophage. Explain this statement.arrow_forwardWhen various strains of λ phage are seeded on a lawn of E. coli, they can form clear or turbid plaques. (b) For mutant λ phages that can only form clear plaques, give two different types of mutation in the phage that can explain the clear plaque phenotype.arrow_forwardWhich of the following terms describes bacteriophage DNA that has become integrated into the host cell chromosome?

- What does a bacteriophage accomplish with lysogeny? O 1) it allows the bacteriophage to destroy the host cell's DNA. 2) it enables the bacteriophage to take over the cell. O 3) it speeds up the viral infection cycle. 4) it allows the bacteriophage to infect cells it would not normally infect. O 5) the genetic material of the bacteriophage can be passed on to future generations of infected cells.arrow_forwardIn Hershey-Chase experiment, bacteriophages protein coats were tagged with radioactive isotope S-32. These phages were used to infect E. coli cells and the cells were further centrifuged to form pellets. Why was the radioactivity level of S-32 found greater outside the cells compared to the E. coli cell pellets? Explain briefly. If the experiment is repeated in the same manner but this time the phage protein coats are labelled with isotope X and the phage DNA with isotope Y, which isotope’s radioactivity will be found in greater amounts in the E. coli cell pellets after centrifugation?
