Question: If antibodies can be brought into contact with a virus before it attaches itself to the host cell, the virus will be inactivated. Once infection has occurred, the production of interferon may protect the host from extensive tissue destruction. Explain.

1. Interferon kills the virus directly
2. Interferon enhances the attachment of viruses to host cells, facilitating the infection process.
3. Interferon is a broad-spectrum antiviral drug that is administered to patients to cure viral infections.
4. Interferon strengthens the virus, making it more difficult for the immune system to eliminate it.
5. Interferon is a type of virus that fights other viruses
6. Interferon is a protein produced by virus-infected cells, which spreads to uninfected cells and makes them more resistant to viral infection. This prevents synthesis of viral proteins which are essential for viral production.
7. Antibodies produce interferon in response to a viral infection, which then inactivates the virus.
8. Interferon is a chemical signal that increases the permeability of cells, allowing antibodies to enter and attack the virus.
9. Interferon triggers the immediate destruction of the host cell to prevent the spread of the virus.
10. Interferon is produced by the virus to weaken the host cell

Our answer: F. Interferon is a protein produced by virus-infected cells, which spreads to uninfected cells and makes them more resistant to viral infection. This prevents synthesis of viral proteins which are essential for viral production. Source quote machine-checked (exact quote)
