Suck My Deck Flashcards
True or False: Most microbes are beneficial to the body rather than harmful
True
Genetically engineered E.Coli can be used to synthesize:
Insulin
He discovered the cell
Robert Hooke - viewed a thin cutting of cork and discovered empty spaces contained by walls which he termed cells.
Observed organisms using a simple light microscope
Anton Van Leeuwenhoek - also called the “Father of Microbiology”
Known for the concept of Biogenesis. Also known as father of pathology
Rudolf Virchow
Developed the aseptic technique
Louis Pasteur - Also created a experiment that microorganisms are in the air everwywhere
famous for his swan-neck flask experiment, which allowed air to contact the broth. Microbes present in the dust were not able to navigate the tortuous bends in the neck of the flask.
Louis Pasteur
disproved spontaneous generation for large organisms by showing that maggots arose from meat only when flies laid eggs in the meat.
Francesco Redi
showed that if a broth was boiled (presumed to kill all life) and then allowed to sit in the open air, it became cloudy.
John Needham
Discovered Mycobacterium Tuberculosis
Robert Koch
Koch’s Postulates
- Microorganisms must be present in every case of the disease and absent from healthy organisms.
- The suspected microorganism must be isolated and grown in a pure culture.
- The same disease must result when an isolated microorganism is inoculated into a healthy host.
- The same microorganism must be isolated again from the diseased host.
Father of Vaccination
Edward Jenner - made a live, attenuated smallpox vaccine
Penicillin
Alexander Fleming
What are the 3 domains of the 3-Domain Scheme
Eukarya, Archaeobacteria, Eubacteria
All three domains from the Three-Domain Scheme arose from this.
Universal Phylogenetic Ancestor
a classification scheme for microbes that compared nucleotide sequences in rRNA from different cell groups
Three-Domain Scheme - created by Carl Woese in 1977 based in molecular biology and biochemistry
a classification scheme created by Robert Whittaker in 1969 that is based on cell type, cellular organization and nutritional pattern
Five-Kingdom scheme
Pa**FAP - **Protista, Fungi, Animalia, Plantae
[Five-Kingdom Scheme] Kingdoms under Prokaryotes
Monera
Differentiate Eukaryotes vs Prokaryotes
Eukaryotes - Membrane-bound nucleus, Extrachromosomal DNA in organelles, semipermeable cytoplasmic membrane, no peptidoglycan in Cell Wall, sterols present, 80s ribosomes in cytoplasmic reticulum
Prokaryotes - No nuclear membrane, just a single circular chromosome; Extrachromosomal DNA in plasmids, cytoplasmic membrane contains enzymes of respiration and serves as site of DNA synthesis, rigid peptidoglycan cell wall (except mycoplasma), absent sterols (except mycoplasma), 70s ribosomes in cytoplasm
Kingdom with most number of organisms
Monera
How do fungi help in bread-making?
CO2 bubbles from fungi respiration help dough to rise
Fungal toxin
Mycotoxin
a mutually beneficial symbiotic relationship between fungi and plant roots
Mycorrhizae
In 1937, he developed the attenuated 17D strain vaccine against yellow fever
Max Theiler
