• A bacteriophage is a type of virus that infects bacteria. • All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure. • A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. • Following infection, 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 to increase their spread. • 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
