Unformatted text preview: atmosphere. - Bacteria cause the atmospheric oxidation, (Oxygen in atmosphere 20% Oxygen). These oxygen molecules create an Ozone layer, which blocks UV Rays from the sun. - The Ultraviolet light mutates DNA. (Dimmers)- Cyanobacteria is globally distributed and lives in any environment Proterozoic (check Evolutionary Diagram, Figure 21.15 in book)- Eukaryotes and Bacteria arose and the same rate- Eubacteria has Peptidoglycan Cell wall- Archaea doesn’t have peptidoglycan cell wall- Eukarya has cell wall made of Cellulose, Chitin (See Table 21.1 for comparison)- In bacteria it folds on its self to stabilize DNA- Eukaryotes and Eubacteria use proteins to package and stabilize DNA (Slide 5, Origin of the nuclear envelope)- The invagination surrounds the nucleus- Secondary Endosymbiosis of Eukaryote Cells.- Plastids have Chlorophyll A /& B...
