Document Summary
Classification and virology: classification and evolution, classification, taxonomy: science of describing, naming, and classifying organisms-binomial nomenclature. Groups from broad to narrow are domain to species. ): grouping of organisms at any one of these levels. Domain, kingdom, phylum, class, order, family, genus, species: phylogeny: evolutionary history of a species or a group of related species. 3 types of diversity: genetic, species, community & ecosystem. Natural selection: differential survival and adaptation: evolution, basics of phylogeny. Phylogeny: evolutionary history of a group (figure 1) Nonliving; no cells-only genetic material and protein; metabolism-requires a cell; reproduction requires a cell. Some viruses have envelopes on top of capsid-comes from host-hides virus: viral reproduction. Eventually a temperate virus hiding using lysogenic cycle may activate; then it will start the lytic cycle. Lytic cycle with a virulent phage (ends in death of host cell) (figure 3) Temperate phage: may stay in lysogenic cycle for years but environmental change triggers switch to lytic (figure 5)
