Flashcards in Chapter 10 Deck (35):
What is "Taxonomy"?
The science of classifying organisms
(shows degree of similarity among organisms)
What is "Phylogeny"?
The study of the evolutionary history of organisms
Who devised the 5-kingdom classification system?
Who created the Kingdom "Prokaryotae"?
He thought of the 3-Domain system
Methanogens, Extreme Halophiles, and Hyperthermophiles all belong to the domain....
Eukaryotic cells have __s ribosomes;
Prokaryotic cells have __s ribosomes
Prokaryotic cells reproduce through _______
Eukaryotic cells reproduce through________
This domain supposedly originated from infoldings of prokaryotic plasma membranes....
All organisms in one phylogenetic tree share a common _______?
(each species retains some characteristics of
Specific Epithets are also known as
Who developed the Taxonomic hierarchy?
Eukaryotic species: a group of _____ related organisms that _____ among themselves
Prokaryotic species: a population of cells with ______ characteristics
What is a bacterial culture?
Bacteria grown in laboratory media
A population of cells derived from a single parent cell
A set of genetically different cells within a clone is known as a....?
What domain do viruses belong to?
What is serology?
The science that studies serum and immune responses in serum
Microorganisms are antigenic—they stimulate the body to form antibodies in the serum
What happens in the slide agglutination test?
Bacteria agglutinate when mixed with antibodies produced in response to the bacteria
Enzyme-linked immunosorbent assay (ELISA) is the best way to identify unknown ______
The Western Blotting test, which identifies antibodies in a patient's serum is most commonly used to confirm a _____ infection
What is "Phage Typing" used for?
Phage Typing is used to determine which phages a bacterium is susceptible to.
(On a plate, clearings called plaques appear where phages infect and lyse bacterial cells)
Fatty acid methyl esters (FAME) provide profiles that are _____ for a particular species
This testing method uses differences in electrical conductivity between species or fluorescence to identify bacteria types?
What is DNA fingerprinting?
Comparing fragments from different organisms which provides information on genetic similarities and differences, which in turn leads to bacteria identification
Nucleic Acid Amplification Tests (NAATs) use PCR to amplify DNA of ________ microorganisms that ______ be cultured
Nucleic acid hybridization measures the ability of ____ strands from one organism to hybridize with ____ strands of another organism
btw: Greater degree of hybridization = greater degree of relatedness
"Southern blotting" uses nucleic acid hybridization to identify unknown microorganisms using ___ _______
___ ______, also known as "microarrays", contain DNA probes and detect pathogens by hybridization between the probe and DNA in the sample.
(btw: They are detected by fluorescence)
Ribotyping is also known as ....
Fluorescent in situ hybridization (FISH) is used to determine three microorganic features in a given environment:
3) Relative Activity
What happens in the Fluorescent in situ hybridization (FISH) test?
Fluorescent DNA or RNA probes stain the microorganisms being targeted
A series of identification keys based on successive questions is known as a ...
