Across
- 4. The viral nucleic acid is released from the capsid
- 6. Nonenveloped and complex viruses released when cell dies and ruptures
- 7. Binding of virus to specific molecule on host cell
- 8. Nucleocapsid (found in all viruses) has 2 parts: Nucleic Acid and Capsid
- 9. New viral particles are constructed
- 11. Spectrum of cells a virus can infect
- 14. Assembly of phage particles into virions (complete infectious virus)
- 15. Phage lysozyme opens cell wall; tail sheath contracts to force tail core and DNA into cell
- 16. Produced naturally by virally infected cells – to magnify an immune response.
- 18. Stops the action of influenza neuraminidase, required for entry of virus into the cell.
- 19. Assembled viruses are released by budding (exocytosis) or cell lysis
Down
- 1. Exposed carbohydrate-protein complexes on the outside of the envelope
- 2. Genome enters host cell
- 3. Production of phage DNA and proteins
- 5. Protein coats that enclose and protect their nucleic acid
- 7. Phage attaches by tail fibers to host cell
- 10. Promotes interferon production
- 12. Surrounds capsid
- 13. Remains in asymptomatic host cell for long periods
- 17. Viral components are produced
