The Outermost Layer of a Virion Fulfills Which of the Following

Question

The outermost layer of a virion fulfills which of the following functions of the virus?
A) protection
B) recognition
C) replication
D) both protection and recognition
E) both recognition and replication

Accepted Answer

The outermost layer of a virion, also called the envelope or capsid, serves both protection and recognition functions. It protects the genetic material of the virus and aids in its transmission, as well as plays a crucial role in recognition and attachment to host cells. It does not directly participate in replication, which occurs within the host cell after the virus has gained entry.
