Chemistry in depth essays 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...
