Multiple Choice
The envelope surrounding enveloped viruses originates from?
A
The host cell's plasma membrane.
B
The parent virus's viral envelope.
C
The host cell creates new viral envelope lipids.
Verified step by step guidance
1
Understand the structure of enveloped viruses: Enveloped viruses have a lipid bilayer surrounding their capsid, which is derived from the host cell's membrane.
Identify the source of the viral envelope: The envelope is typically acquired from the host cell's plasma membrane during the process of viral budding.
Differentiate between the viral envelope and the host cell's membrane: While the envelope originates from the host cell's membrane, it may contain viral proteins that are inserted into the membrane during viral replication.
Consider the process of viral budding: During budding, the virus takes a portion of the host cell's membrane, which becomes the viral envelope, allowing the virus to exit the host cell.
Clarify misconceptions: The host cell does not create new viral envelope lipids; instead, the virus utilizes the existing lipids from the host cell's plasma membrane.
