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