BIOL 1202 : Biology Exam 2
Document Summary
1: boundaries between units in the geologic time scale are marked by dramatic biotic change, 5 kingdom classification system in use through the late 1900s gave way to woese"s 3. These contributions combine in the modern branches: taxonomy naming & classifying organisms, systematic phylogenetics, systematics naming & classifying organisms according to their evolutionary relationships, phylogenetics reconstructing the evolutionary relationships among organisms. 2: paraphyletic group consists of an ancestor & some of its descendants. We almost never have a continuous record from one species to the next. Cladistic principles allow us to construct hypothesized phylogenetic trees. Each key character originated (evolved) once. (34: (35) Chapter 27 & 28: the hidden world of microbes. Dna or rna: capsid protein coat which surrounds & protects genome, envelope membrane (phospholipid bilayer) which surrounds the capsid, hijack cells the entire function of a virus is to take control of a host cell to produce more virus particles.
