Prokaryotes Flashcards
1
Q
Compare prokaryotes with eukaryotes [7]
A
Unicellular vs. multicellular; no membrane bound organelles; circular vs. linear DNA; 70s vs 80s ribosomes; binary fission vs asexual/sexual; peptidoglycan vs cellulose/chitin in fungi cell walls; both have cytoskeleton and membrane
2
Q
What is it’s DNA structure?
A
One chromosome; genes often grouped in operons; same structure different package
3
Q
Flagella function, structure & process?
A
Thinner and does not have the 9 + 2 arrangement; chemiosmosis supplies energy to rotate the filament that forms the flagellum; attached to membrane by basal body (hook) and rotated by molecular motor
4
Q
Cell wall structure?
A
Made of peptidoglycan
