Exam III Flashcards
(32 cards)
Lytic cycle
Viral DNA is assembled inside host cell
Lysogenic cycle
Viral DNA is integrated into host cell’s genome
Flagella
tail-like structures; SPIN
Prions
PROTEIN that causes disease; i.e. Mad Cow Disease
Virus
Single-celled organism relying on host cell; make new generation of viruses
Cocci bacteria
Circular
Bacilli bacteria
Rod-shaped
Spirilli bacteria
spiral-shaped
Strep bacteria
chained
Staph bacteria
clustered
Gram + bacteria
THICK cell wall; glycoprotein; more resistant to antibiotics
Gram - bacteria
Thin cell wall; more susceptible to antibiotics
Axial filaments
squigilly proteins that expand and contract through tissue
“gliding motility”
unexplained
Koch’s Postulates
Find same germ in diseased individuals (not in healthy ones), organism must be isolated and grown away from HOST, if grown bacteria is injected in healthy person they should get the disease, organism grown again should be THE SAME as the the original.
Mutualism
species living closer together
Commensalism
1 species benefitting; bacteria living on skin
Parasite
1 species benefits, the other suffers
What is the dominant stage of mosses?
Gametophyte
What is the dominant stage of ferns?
Sporophyte
Haustorium
(fungi) Penetrates hosts’ tissue, benefits from it
Chytrids
aquatic fungi; have both spores and gametes (w/flagella)
Ascomycetes
produce ascospores (spore-producing structures) i.e. cupped fungi and yeast
Zygomycets
where two mating types must fuse together
