Final answer:
The capsid is the protein coat that makes the head of a bacteriophage. The tail fibers contain binding sites that recognize areas on the outer surface of the bacterial cell wall.
Step-by-step explanation:
In biology, the protein coat that makes the head of a bacteriophage is called a capsid.
The tail fibers of the bacteriophage contain binding sites that recognize specific areas on the outer surface of the bacterial cell wall, allowing the virus to attach to the cell and infect it.
