Across
- 2. putting together new virions
- 4. experts estimate that 20% of cancers are caused by this
- 5. a disease that afflicts the central nervous system, causes degeneration and death, and is acquired in multiple ways
- 8. a fully formed virus that is able to establish an infection in a host cell
- 9. viruses can cause formation of inclusion bodies in either the cytoplasm/nucleus of the host cell. Rabie virus infected cells accumulate structures called Negri bodies in their cytoplasm
- 10. damage to host cell by a virus
- 12. most contain double-stranded DNA as main genetic material, found everywhere but prominent in sewage and water environments
- 14. within cell cytoplasm
- 15. A disease in tobacco plants caused by a virus ( 1st Discovery of Virus)
- 16. a classification system where it is based on a virus nucleic acid and how it is produced
- 19. defined as areas where virus-infected cells have been destroyed
- 20. virus like agent that infect plants
- 21. can be dsDNA, ssDNA, ssRNA, dsRNA
- 22. laboratory-bred animals and embryonic bird tissues
Down
- 1. cell or tissue culture methods
- 3. fat redistribution, "buffalo hump"
- 6. when bacteriophages infect, but remain dormant, not destroying the target cell, it is called this
- 7. composed of protein (no nucleic acid), exact mode of infection is still being investigated
- 11. new visions leave host cell and infect other cells
- 13. replication viral genetic material
- 17. getting into host cell
- 18. external protein shell
