  1. 2 characteristics of protists
    Eukaryotic and unicellular
  2. 3 Difference between protists vs bacteria and Archarea
    • 1) have organelles (including nucleus)
    • 2) Don't have peptedoglycan.
    • 3) Larger than bacteria and archarea.
  3. How are protists different from fungi? cell wall, & spore formation
    • 1) don't produce spores
    • 2) Don't have chitan in cell wall
  4. Animal like protists are called
    protozoans
  5. Plant-like protists are called
    Unicellular alfae
  6. 2 types of Fungus-like protists:
    slime and water molds.
  7. Virus replication cycle? 5 steps
    • 1) Attachment
    • 2) Entry
    • 3) Synthesis
    • 4) Assembly
    • 5) Release
  8. 3 major routs of entry
    • 1)injection
    • 2) fusion
    • 3) Endocytosis
  9. 2 routs of exit
    lysis and budding
  10. Name of viruses that infect bacteria
    bacteriophages
  11. Typical lytic infection where destruction of host cell occurs
    Acute, and infects eukaryotic cells
  12. Latent infections are
    infects eukaryotic cells. lysogenic infections of bacteria that lay dormant, no virons are produced, and host doesn't die unless it becomes an acute infection.
  13. Chronic
    Infects eukaryotic cells: Long lasting, but the host cell doesn't die.
  14. 4 variations in replication cycle of viral infected eukaryotic cells.
    • 1) acute,
    • 2) Latent
    • 3) Chronic
    • 4) Transformation
  15. How does the viral infected replication cycle variation, Transformation, cause cancer in Eukaryotic cells?
    by turning on host cell genes called oncogenes, and turning off tumor suppressor genes.
  16. What's causes prion diseases
    Prions change the folds of normal proteins in the same way to form crystals and poke holes in the PM of the cell.
  17. Viroids are
    Tiny nucleic acid RNA with no protein capsid.
  18. 3 Parts of the lytic cycle
    • 1) injection of genetic material
    • 2) Synthesis of DNA & protein
    • 3) Release of virus
  19. What microorganism is described:
    -no known nucleic acid components
    -causes neurodegenerative diseases
    -incorrectly folded protein
    prions
