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. AVPs are part of the cell's defense mechanism against viral infections.

Recognize that double-stranded RNA (dsRNA) is often a sign of viral infection, as many viruses produce dsRNA during replication.

Learn that when a cell detects dsRNA, it can activate antiviral proteins. These proteins are initially inactive and become activated upon encountering dsRNA.

Explore the process of apoptosis, which is a programmed cell death. This is a mechanism to prevent the spread of viral infection by sacrificing the infected cell.

Understand that the activation of antiviral proteins can lead to apoptosis, effectively stopping the production of viral particles and preventing the virus from spreading to neighboring cells.
