Across
  1. 2. projections from the outer surface of a virus
  2. 4. remains asymptomatic in host cell for long periods of time
  3. 8. viruses attach to cell membrane to multiplicate
  4. 10. protein coat made of capsomeres
  5. 12. occurs gradually over long periods, generally fatal
  6. 13. separating viral nucleic acid from capsid by viral or host enzymes to mulitplicate
  7. 15. lipid, protein and carbohydrate coating on some viruses
  8. 17. double-stranded DNA, enveloped, cause skin lesions and smallpox
Down
  1. 1. double-stranded DNA, enveloped, cause cold sores, chickenpox, infectious mononucleosis
  2. 3. genes that encode proteins involved in stimulating normal cell growth, when mutated they become oncogenes
  3. 5. production of nucleic acid and proteins
  4. 6. single-stranded RNA, nonenveloped, include poliovirus and common cold
  5. 7. nucleic acid and capsid proteins assemble for multiplication
  6. 9. single-stranded RNA, envleoped, causes COVID-19 along with 4 other species that cause mild respiratory infections
  7. 11. infections protein particles
  8. 14. double-stranded DNA, noneveloped, cause respiratory infections in humans
  9. 16. virus enters cell by recpetor-mediated enodcytosis or fusion to multiplicate
