Question

Where do enveloped viruses typically acquire their lipid bilayer membrane from?
Options

B They derive it from host cell membranes during viral release.
Correct Answer
C It is a fixed component pre-assembled within the virion.
D From other enveloped viruses during co-infection.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Under 'Envelope', the document explains: 'The lipid bilayer is derived from host cell membranes during viral release, but virus-specific proteins replace the proteins.'

Hint

The envelope is an 'extra' layer for some viruses; consider its origin in relation to the host.
