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.
