3 Difference between protists vs bacteria and Archarea
1) have organelles (including nucleus)
2) Don't have peptedoglycan.
3) Larger than bacteria and archarea.
How are protists different from fungi? cell wall, & spore formation
1) don't produce spores
2) Don't have chitan in cell wall
Animal like protists are called
protozoans
Plant-like protists are called
Unicellular alfae
2 types of Fungus-like protists:
slime and water molds.
Virus replication cycle? 5 steps
1) Attachment
2) Entry
3) Synthesis
4) Assembly
5) Release
3 major routs of entry
1)injection
2) fusion
3) Endocytosis
2 routs of exit
lysis and budding
Name of viruses that infect bacteria
bacteriophages
Typical lytic infection where destruction of host cell occurs
Acute, and infects eukaryotic cells
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.
Chronic
Infects eukaryotic cells: Long lasting, but the host cell doesn't die.
4 variations in replication cycle of viral infected eukaryotic cells.
1) acute,
2) Latent
3) Chronic
4) Transformation
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.
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.
Viroids are
Tiny nucleic acid RNA with no protein capsid.
3 Parts of the lytic cycle
1) injection of genetic material
2) Synthesis of DNA & protein
3) Release of virus
What microorganism is described:
-no known nucleic acid components
-causes neurodegenerative diseases
-incorrectly folded protein
