Most enveloped viruses, like hepatitis B, are released by budding, a process whereby the virus acquires its envelope. Before budding occurs, virally encoded protein spikes insert into specific regions of the host cell's membrane. Given this information, which of the following would you tell your friend best describes the structure of the viral envelope?
A) Phospholipid bilayer
B) Phospholipid bilayer with host-derived proteins.
C) Phospholipid bilayer studded with both virus- and host-derived proteins.
D) Protein layer with host-derived spikes.
E) Phospholipid monolayer studded with virus- and host-derived proteins.

Quizplus · Accepted Answer

The viral envelope is composed of a phospholipid bilayer studded with both virus- and host-derived proteins. The virally encoded protein spikes insert into specific regions of the host cell's membrane to acquire this envelope.
