You are studying an unknown virus and note that upon contact with a specific host, the virus's terminal tail fibres attach and the outer layer twists and contracts. This forces the core of the virus's tail through the host's cell membrane such that the viral genome enters the host. Based on this information, the host for this virus must be a
A) plant.
B) animal.
C) bacteria.
D) fungi.
E) the virus could infect any host.

Question

Quizplus · Accepted Answer
