Antiviral medications work by inhibiting or stopping a stage of viral replication. Which statements are descriptions of these stages?
Standard Text: Select all that apply.
Choice 1. Attachment of the virus to the host cell
Choice 2. Destruction of host cell DNA.
Choice 3. Synthesis of the viral nucleic acid and proteins by the host cell
Choice 4. Assembly of all viral components, structural proteins, enzymes, and nucleic acids
Choice 5. Release of virions from the host cell
Correct Answer: 1,3,4,5
Rationale 1: The first stage of viral infection is the attachment of the virus to the host cell.
Rationale 2: Destruction of host cell DNA is not a stage of infection.
Rationale 3: The third stage of viral infection is synthesis of the viral nucleic acid and proteins by the host cell.
Rationale 4: The fourth stage of viral infection is assembly. All the viral components, structural proteins, enzymes, and nucleic acids are packaged and made ready to leave the cell.
Rationale 5: The fifth stage of viral infection is the release of the virions from the host cell.
Global Rationale: The stages of viral infection are attachment of the virus to the host cell, penetration, synthesis, assembly, and release of the virions from the host cell.
