Across
  1. 4. most frequently causes the "common cold"
  2. 7. __ viruses that co-infect host cells and help defective viruses replicate
  3. 10. rogue proteins that are infectious and cause fatal neurological diseases in mammals
  4. 12. recombination of segments of genomes between two viruses in a single host that results in a new virus
  5. 13. viruses with a 20-sided dice morphology
  6. 16. small naked RNA molecules that cause disease in plants
  7. 17. stage of viral cycle where virus binds to host cell membrane
  8. 18. periodic outbreaks occur in West Africa, causes hemorrhagic fevers and believed to come from bats
  9. 19. used to be a common childhood virus caused by varicella-zoster virus
  10. 21. point mutation leads to small changes in spike proteins of viruses
  11. 22. stage where viruses leave host cell
Down
  1. 1. derived from host cell membrane when virus leaves
  2. 2. causes warts in any part of the body and has over 200 strains
  3. 3. __viruses that lack genes to replicate in hosts and depend on other larger viruses
  4. 5. cycle viral life cycle characterized by long periods of viral dormancy in host cell
  5. 6. proteins or glycoproteins that help viruses attach to host cells
  6. 8. close to being eradicated worldwide, caused thousands of cases of paralysis in children in the US in the 1950s
  7. 9. stage of viral cycle where nucleic acids are released from the capsid
  8. 11. made of repeating capsomere proteins, protects viral genome
  9. 14. viruses that have a thread-like morphology
  10. 15. bacteriophages fall into this morphology group
  11. 20. cycle viral life cycle characterized by immediate replication of viruses in new host cell
