Bacteriophages are viruses that infect bacteria and generally have three main components (head, tail, tail fibres).
A bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material.
Typically, a common bacteriophage has three main components: the head which stores genetic material, the tail, which is a passageway for genetic material to be injected into host bacteria. The end contains tail fibres which help the bacteriophage attach to the host bacteria.

• A typical bacteriophage has three main components: head, tail, and tail fibres.
bacteriophage: viruses that infect bacteria
head: stores phages’ genetic material
tail: passageway for phages’ genetic material to be injected into bacteria
tail fibres: help phages attach to the host bacteria
