Archaeobacteria-prokaryotic organisms lacking peptidoglycan in their cell walls and differing from eubacteria in many ways.
Binomial nomenclature-by Linnaeus where each organism is assigned a genus and specific epithet (2nd name)
Cyanobacteria-photosynthetic, prokaryotic, typically unicellular organisms that are members of kingdom Monera
Divergent evolution-process where descendents of a common ancestor species undergo sufficient change to be identified as separate species
DNA hybridization-process where double strands of DNA of ea. Of 2 organisms are split apart and split strands from 2 organisms are allowed to combine
Domain-new taxonomic category above kingdom level, consisting of Archae, Bacteria, and Eukarya
Eukaryote-organism with eukaryotic cells (w/nucleus and other membrane bound structures
Extreme halophile-grow in highly saline (salty) environments. Generally obligate aerobes
Extreme thermoacidophile-require hot and acidic environment usually from Domain Archae
Five-kingdom system-system of classifying organisms into one of 5 kingdoms: Monera (prokaryotae), Protista, Fungi, Plantae, and Animalia
Fungi-kingdom of nonphotosynthetic, eukaryotic organisms that absorb nutrients from their environment
Genetic homology-similarity of DNA base sequences among organisms
Genus-taxon consisting of one or more species (1st name)
Methanogen-one of groups of Archaeobacteria that produce methane gas
Monera-(prokaryote) kingdom of prokaryotic organisms that are unicellular and lack true cell nucleus
Mycoplasmas-very sm. Bacteria w/ cell membranes, RNA, and DNA, but no cell walls
Numerical taxonomy-comparison of organisms based on quantitative assessment of a lg. # of characteristics
Phage typing-use of bacteriophages to determine similarities or differences among different bacteria
Phylogenetic-pertaining to evolutionary relationships
Polyacrylamide gel electrophoresis (PAGE)-a technique for separating p...
