BIOL 209 EXAM 1
Louis Pasteur
-Pasteurization
-Formulated the germ theory.
-Discredited the idea of spontaneous generation ("microbes just appeared")
Robert Koch
-Postulates; finalized the germ theory
-Isolated a single bacteria cell and putting it in an animal
-Came up with colonies
-Focused on isolation with Pasteur
Alexander Fleming
- Discovered penicillin-mold was destroying his colonies
-proved as an antibiotic
-Antibiotics
Anton von Leeuwenhoek
- Grind glasses for lenses in microscopes
-Used to see microscopic organisms
-Animalcules
Joseph Lister
-Antiseptic technique
-Carbolic Acid spray during surgery
Franny Hesse
, Created the agar plate, first composed of seaweed, gelatin melted in the incubator, bacteria
would produce that broke down the gelatin.
Walter Reed
-Discovered that the mosquito transmitted yellow fever and developed a cure.
-Zoonotic Transmission (animal to human)
What are the three domains of organisms?
- Bacteria, Archaea, Eukarya
Why are the three domains of organisms separated into domains?
- They are separated by the type of rRNA (found in ribosomes) and cellular functions that the
organisms have.
What specific microbial genetic material did Woese use to different Prokaryote (bacteria)?
-Cell Membrane
-Single Celled
-No true Nucleus
-Cellular DNA
-Has Peptidoglycan
What specific microbial genetic material did Woese use to different Eukaryote?
-Single celled or multi celled
-True Nucleus
-Have membrane bound organelles
-Plasma membrane
-No peptidoglycan
-DNA is linear
-Pathogenic (sometimes)
What specific microbial genetic material did Woese use to different Archaea?
