Which Activity of the Virally Invaded Cell Triggers Production of Interferon

Question

Which activity of the virally invaded cell triggers production of interferon?
A) Activation of rRNA
B) Movement of nuclear proteins to the cytoplasm
C) Production of glycolipids
D) Production of dsRNA
E) Production of dsDNA

Accepted Answer

Production of dsRNA in the virally invaded cell triggers production of interferon. This is because dsRNA is a molecular structure that is not normally present in the host cell, and therefore recognized as foreign by the cell. Production of dsRNA is a common feature of many viral infections, and the presence of dsRNA in the cell is a signal of viral invasion. The production of interferon is part of the cell's immune response to the viral infection, and is intended to prevent the virus from replicating and spreading to other cells.
