Question

Interferons α and β are released from ________ and act to inhibit viral replication by ________.

A) infected cells : degrading RNA
B) neutrophils : digesting the virus
C) phagocytotic cells : digesting the virus
D) phagocytotic cells : degrading RNA
E) T lymphocytes : degrading RNA

Answer 1

Interferons α and β are released by infected cells to inhibit viral replication by degrading RNA, thereby preventing the virus from producing more copies of itself.

Step-by-step explanation:

Interferons α and β are released from infected cells and act to inhibit viral replication by signaling nearby uninfected cells to destroy RNA and reduce protein synthesis, activate immune cells, and prompt infected cells to undergo apoptosis. Therefore, the correct answer to the student's question is A) infected cells : degrading RNA.
