- Interferons are synthesized by cells in response to many different viral infections. The common result of the interferon-induced antiviral state is the cessation of protein synthesis. Predict the effect of the following treatments of the indicated cell on protein synthesis in that cell.

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
