Question

Quizplus · Accepted Answer

Interferon triggers the production of virus-blocking enzymes by cells that have not yet been invaded by viruses. It does not directly break down viral messenger RNA and inhibit protein synthesis, as stated in option C. Option A is incorrect because interferon is released from virus-infected cells, not bacteria-infected cells. Option D is also incorrect because exercise can actually increase interferon secretion.
