Question

Given below is the diagram of a bacteriophage.

Select the option that correctly identifies a, b, c and d

Answer 1

Bacteriophages are viruses which infect bacteria.

The structure of a typical bacteriophage includes a head and a tail.

The geometrically shaped head contains protein, and stores the genetic material.

From the head, runs the tail, which is a hollow tube that serves as a passageway for the genetic material to pass from the capsid to the host bacteria.

The entire tail is covered with a sheath. Tail fibers present at the bottom of the tail are used to securely attach the bacteriophage to the bacterial surface. These fibers contract during an infection.
