The head and tail of the bacteriophage are constructed from proteins. The head contains the viral DNA and the tail is a hollow tube used to inject a host cell during infection, though not all phages have a tail. WebViruses belonging to the Myoviridae family have long contractile tails, which are formed by the following parts: the baseplate, which is the part in charge of the contact with the surface of the host cell; the sheath, which builds the outer protein cylinder of the tail and provides a contractile capacity; the tail tube, which assembles the inner... french bedroom set
