Multiple Choice

If a cell produces antiviral proteins (AVPs) what occurs when that cell encounters dsRNA?

The antiviral proteins trigger the production of iAVPs.

The antiviral proteins cease protein translation in the cell so no viral proteins can be made.

The antiviral proteins become activated and the cell undergoes apoptosis to stop the viral spread.

The antiviral proteins trigger the production of interferon proteins to warn neighboring cells of viral infection.

Verified step by step guidance

Understand the role of antiviral proteins (AVPs) in the cell's defense mechanism against viral infections. AVPs are part of the innate immune response and are produced in response to viral infections.

Recognize that double-stranded RNA (dsRNA) is often a molecular pattern associated with viral infections, as many viruses produce dsRNA during their replication cycle.

Learn that when a cell encounters dsRNA, it can activate antiviral proteins that have been produced in response to the viral infection. This activation is a key step in the cell's defense strategy.

Explore the concept of apoptosis, which is a programmed cell death mechanism. When antiviral proteins are activated by dsRNA, they can induce apoptosis to prevent the virus from using the cell's machinery to replicate and spread.

Consider the broader immune response, where activated antiviral proteins can also lead to the production of interferon proteins. These proteins serve as signaling molecules to alert neighboring cells of the viral presence, enhancing the overall immune response.
