A bacterial strain is resistant to infection by a bacteriophage. Which statement is false?

A) The bacteriophage injects its genetic material into the bacterial cell.
B) The bacterial strain lacks a receptor recognized by the bacteriophage.
C) The bacteriophage cannot adsorb to the bacterial cell.
D) The bacterial cell has a defense mechanism preventing phage entry.

Answer :

Final answer:

The statement that is false is The bacterial strain lacks a receptor recognized by the bacteriophage. The correct option is (b) he bacterial strain lacks a receptor recognized by the bacteriophage.

Explanation:

The False statement is The bacterial strain lacks a receptor recognized by the bacteriophage. In order for a bacteriophage to infect a bacterial cell, it must first adsorb to the bacterial cell. The adsorption process involves the recognition and binding of the bacteriophage to specific receptors on the surface of the bacterial cell. If the bacterial strain lacks the receptor recognized by the bacteriophage, the bacteriophage cannot adsorb to the bacterial cell and therefore cannot infect it.
