Antibody Produced in Response to a Viral Infection is Able

Question

Antibody produced in response to a viral infection is able to neutralize viral attachment by
A)binding nucleic acid polymerases and preventing viral nucleic acid replication.
B)binding ribosomes and preventing viral protein translation.
C)activating macrophages to phagocytize the virus.
D)binding to the viral attachment proteins to prevent attachment to the host cell receptor.
E)binding to the host cell receptor molecule to prevent the attachment of the virus.

Accepted Answer

Antibodies are proteins that are produced by the body's immune system in response to an infection. One of the ways in which antibodies can neutralize viruses is by binding to viral attachment proteins, which are proteins on the surface of the virus that allow it to attach to and enter host cells. By binding to these attachment proteins, antibodies can prevent the virus from attaching to the host cell and therefore prevent infection. Option A and B refer to steps in viral replication; Option C is an indirect way of combating the virus by recruiting immune cells to clear the infection, whereas Option E is incorrect because the host cell receptor doesn't interact with viral antibodies.
