Question 2

Genetically engineered E.Coli can be used to synthesize:

Answer 2

Insulin

Question 3

He discovered the cell

Answer 3

Robert Hooke - viewed a thin cutting of cork and discovered empty spaces contained by walls which he termed cells.

Question 4

Observed organisms using a simple light microscope

Answer 4

Anton Van Leeuwenhoek - also called the “Father of Microbiology”

Question 5

Known for the concept of Biogenesis. Also known as father of pathology

Answer 5

Rudolf Virchow

Question 6

Developed the aseptic technique

Answer 6

Louis Pasteur - Also created a experiment that microorganisms are in the air everwywhere

Question 7

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.

Answer 7

Louis Pasteur

Question 8

disproved spontaneous generation for large organisms by showing that maggots arose from meat only when flies laid eggs in the meat.

Answer 8

Francesco Redi

Question 9

showed that if a broth was boiled (presumed to kill all life) and then allowed to sit in the open air, it became cloudy.

Answer 9

John Needham

Question 10

Discovered Mycobacterium Tuberculosis

Answer 10

Robert Koch

Question 11

Koch’s Postulates

Answer 11

1. Microorganisms must be present in every case of the disease and absent from healthy organisms.
2. The suspected microorganism must be isolated and grown in a pure culture.
3. The same disease must result when an isolated microorganism is inoculated into a healthy host.
4. The same microorganism must be isolated again from the diseased host.

Answer 14

Eukarya, Archaeobacteria, Eubacteria

Question 15

Answer 15

Universal Phylogenetic Ancestor

Question 16

a classification scheme for microbes that compared nucleotide sequences in rRNA from different cell groups

Answer 16

Three-Domain Scheme - created by Carl Woese in 1977 based in molecular biology and biochemistry

Question 17

a classification scheme created by Robert Whittaker in 1969 that is based on cell type, cellular organization and nutritional pattern

Answer 17

Five-Kingdom scheme

Answer 18

Pa**FAP - **Protista, Fungi, Animalia, Plantae

Question 19

[Five-Kingdom Scheme] Kingdoms under Prokaryotes

Answer 19

Monera

Question 20

Differentiate Eukaryotes vs Prokaryotes

Answer 20

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

Question 21

Kingdom with most number of organisms

Answer 21

Monera

Question 22

How do fungi help in bread-making?

Answer 22

CO2 bubbles from fungi respiration help dough to rise

Mycorrhizae

In 1937, he developed the attenuated 17D strain vaccine against yellow fever

Answer 25

Max Theiler
