Document Summary
Get the sequence of an ubiquitous gene (like the 16s ribosomal rna gene) for all the organisms to be included in the phylogenetic tree. Align the gene sequences using a sequence alignment program. Science of taxonomy or systematic includes: classification (biological class. , nomenclature (how to n ame organisms, identification (visible characteristics) Goals, stability, predictability, build larger groups, study one member and learn about group. 18th century, carolus linnaeus, linnaeus scheme of classification. Darwin : kingdom or domain, phylum or division, class, order, family, genus, species (basic taxon) Basic taxon in bacterial taxonomy is the species. The names are binomial and are a binary combination of latin words. They consist of a genus name and a single epithet. The genus name has an initial capital letter. They tell us about the organism (appearance, habitat, characteristic property, scientist name). A collection of strains that share many stable properties and differ significantly from other groups of strains.
