7 Cards in this Set
- Front
- Back
|
Organelles
|
No membrane bound organelles.
Nucleoid, circular DNA w one replication origin. |
|
|
Plasmids
|
dsDNA w genes not indispesable to the cell
ex) F plasmids=> genes for conjugation Rplasmids=> genes for resistance against antibiotics |
|
|
Cytoplasma
|
without cytoskeleton and MOSTLY without organelles
All DNA replication etc takes place here due to no nucleus |
|
|
Cell wall
|
have cell wall, exception mycoplasma cells.
Gram+ only peptidoglycans Gram- supplemented eith lipopolysaccharide coat |
|
|
Metabolism
|
Phototrophic - photosynthesis
Chemotrophic (lito-/organotrophic) - Oxidation of chemicals |
|
|
Procaryotes vs Eucaryotes
|
P: 1-10um, 1000-4000 genes, no regular nucleus
E: 5-100um, 10 000 - 30 000 genes, regular nucleus (membrane bound) P: non.mitotic division, transcription and translation both in cytoplasm E: mitotic division, transcription in nucleus translation in cytosol Ribosomes; P 70S, E 80S |
|
|
Archea vs Bacteria
|
Archea are more alike eucaryotes: with chromosomal DNA organized in a structure similar to nucleosomes
tRNA & rRNA contain introns cell wall from pseudopeptidoglycan |
