Document Summary
Concepts and terms to know: phylogenetic analysis, used to trace viral infections through a human population, hiv transmission: Ex: 2 organisms having the same color coat hair makes them homologous to each other: three types of homology: a. i. Hox genes are more similar in closely related species and less similar in more distantly related species. o. Archaea have more complex rna polymerases than bacteria. Archaea have different membrane lipid bonding from bacteria and eukarya. Adhesion between cells: for example: cadherins in animals; pectins in plants. Communication between cells: for example: gap junctions in animals, plasmodesmata in plants. Coordinated growth & cell differentiation (and the underlying genetic program: single-celled organisms may take different forms over time multicellular organisms do this in space rather than in time. No cellulose to stay upright because their structure is supported by water. All leaves are thin and in contact with environment so each cell can make its own food.
