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