Correct Answer - Option 1 : A virus

The correct answer is A virus.

  • A bacteriophage is a type of virus that infects bacteria.
  • The word "bacteriophage" literally means "bacteria eater", because bacteriophages destroy their host cells.
  • The bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components.
  • The new bacteriophages assemble and burst out of the bacterium in a process called lysis.
  • Bacteriophages occasionally remove a portion of their host cells' bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells.
    • This process is known as transduction.
