An Antibiotic Is Added to a Culture of E

question 110

Multiple Choice

An antibiotic is added to a culture of E. coli, resulting in death of the cells. Bacteriophages are then added. Would the phages replicate in the E. coli cells? Why or why not?

• A) Yes, because the cellular machinery of the bacteria is most likely still active. The bacteriophages could use that machinery to replicate new virus particles.
• B) No, because the bacteriophages would depend too much on having the active machinery of a living host cell for replication. 
• C) Yes, because bacteriophages are capable of reanimating dead cells to force them to produce more virus particles.
• D) No, because entry of the bacteriophages into the target cell is dependent on the cell being alive to conduct endocytosis of the virus.
• E) No, because dead E. coli cells do not have any receptors on their cell walls to which the bacteriophages can attach for entry into the host cell by fusion.
