Unit 3: Prokaryotic Cells
Prokaryotes have a much simpler cell structure than eukaryotes.
All organisms are classified into three domains (archaea, eubacteria, and eukaryote)
Prokaryotes have a simple cell structure without compartmentalization.
Drawings of the ultrastructure of prokaryotic cells based on electron micrographs (include cell wall, pili, flagella, plasma membrane, cytoplasm, 70s ribosomes, nucleoid with naked DNA).
Prokaryotes have one chromosome consisting of a circular DNA molecule.
Some prokaryotes also have plasmids but eukaryotes do not.
Antibiotic blocks processes that occur in prokaryotic cells but not in eukaryotic cells.
Florey and Chain’s experiments to test penicillin on bacterial infections in mice.
Risks associated with scientific research-Florey and Chain's tests on safety of penicillin would not be compliant with current protocol on testing.
Viruses lack a metabolism and cannot therefore be treated with antibiotics.
