Understanding Viruses

What is the primary function of a virus once it enters a host cell?

• To destroy the host cell immediately

• To take over the cell's machinery to produce new viruses

• To convert the host cell into a different type of cell

• To protect the host cell from other infections

How do viruses determine which cells to infect?

• By the size of the cell

• By the color of the cell

• By the type of protein receptors on the cell surface

• By the temperature of the cell

What is the role of viral DNA once inside the host cell?

• To destroy the host cell's DNA

• To be transcribed into RNA for new virus production

• To change the host cell's function

• To protect the host cell from other viruses

What happens to the host cell when new viruses are ready to emerge?

• The host cell changes its function

• The host cell becomes immune to further infections

• The host cell often dies

• The host cell becomes stronger

How do antiviral drugs help in controlling viral infections?

• By making the virus more visible to the immune system

• By converting the virus into a harmless form

• By targeting specific points in the virus life cycle

• By strengthening the host cell
