Tetherin is an important protein produced by the host.What is the function of tetherin in protecting a host cell from HIV?
A) ties maturing virions to the membrane of the host cell, thereby preventing the release of the mature virus
B) binds the virus to the external host cell membrane, thereby preventing the virus from entering the host cell
C) binds the viral RNA to reverse transcriptase, thus preventing synthesis of the viral DNA
D) binds the two viral RNA strands together, thus preventing the transcription of viral DNA in the host cell
E) causes the maturing virions to aggregate together, thus preventing their release from the host cell

Tetherin binds to the maturing virions produced by the host cell and tethers them to the host cell membrane, preventing their release and spread to other cells. This limits the spread of the virus and provides a defense mechanism against HIV.
