Bacteriophage is used to infect bacterial cells in culture grown under unfavorable conditions. What will most likely occur?
Luda [366]

When bacteriophage is used to infect bacterial cells in culture grown under unfavorable conditions, it will incorporate its genomic DNA into the bacterial genome.

Bacteriophage, also known as a phage, is a virus which infects and replicates within bacteria. Bacteriophages contain DNA or RNA genome which is encapsulated in a protein coat.

Bacteriophages infect the bacterial cultures. When they infect the bacteria, the genomic DNA of the bacteriophage enters into the bacterial genome. It then replicates within the bacteria. It hijacks its cellular machinery so that it can and does not allow it to produce bacterial components anymore and rather produce viral components.
