  1. 2. This is caused by a prophage-carrying bacterium, producing a toxin, harming lining of upper respiratory tract which restricts breathing.
  2. 3. Viruses can only reproduce using the metabolic machinery of what cell?
  3. 7. Viral particles release in a bud & obtains a membranous envelope.
  4. 9. (2nd) Host cell ENGULFS virus or virus INJECTS its genome into the cytoplasm
  5. 12. Type of virus that is spherical, containing outer spikes above the envelope. (RNA & capsid = inner parts)
  6. 14. A latent viral DNA in the lysogenic cycle is called a what?
  7. 17. (2 words) Retroviruses contain this where RNA -> cDNA is carried out & cDNA integrates into host DNA.
  8. 18. (5th) New viruses EXIT host cell through lysis or budding in order to INFECT new host cells
  9. 19. Naked strands of RNA that contribute to CROP diseases.
  10. 20. Viral reproduction does not happen immediately, virus integrates into a host genome & may reenter lytic cycle.
  11. 23. (L) Viral reproduction occurs, host cell goes through lysis (burst) & release of many viral particles.
  12. 24. (2 words) What type of core do viruses have? (Hint: DNA or RNA)
  13. 26. (2 words) Type of virus that has a coiled-shaped RNA making up the whole capsid.
  14. 27. What part of the lysogenic cycle follows after penetration?
Down
  1. 1. (&) Viruses are characterized by 2 structures which are:
  2. 4. These viruses infect BACTERIAL cells & also have 2 life cycles!
  3. 5. HIV, the virus that causes AIDS
  4. 6. Protein molecules w/ contagious tertiary structure (like neurogenerative diseases)
  5. 8. A type of virus with a hexagon-shaped capsid.
  6. 10. (4th) Viral components are assembled into NEW VIRUSES
  7. 11. The outer layer made up of protein subunits, either naked or enveloped by membrane.
  8. 13. (hyp) Viruses are considered living/non-living?
  9. 15. (hyp) This bacteriophage is shaped like a spider (Head = capsid, Legs = tail fibers).
  10. 16. (3rd) NEW viral components are synthesized using host cell’s machinery and energy
  11. 21. These intracellular parasites cannot reproduce outside a living cell & are either active or not.
  12. 22. This type of virus enters a host cell, uncoating releases of viral DNA/RNA.
  13. 25. (1st) Virus ENTERS a host cell based on host-specific match between virus surface molecules & host cell receptors.
