Document Summary

Know the main cell structures and their differences between prokaryotes and eukaryotes. Unique cell wall sugars linked by weird amino acids. 3 challenges: energy transformation (more variety, reproduction (dna replicates and then cell splits, plasmids, response to environment - endospores (essentially inactive for dna exchange) Anthrax, botulism), chemotaxis (swim towards high concentration, chemical gradient, and move with flagella) Cell wall gram stain shows purple (if purple, peptidoglycan about 5x thicker, if not purple there is a thin peptidoglycan and 2nd outer lipid membrane: more modern classification is based on dna sequencing. Relationships based on dna similarity - phylogeny. If we wanted to eliminate all bacteria: unlike virus, bacteria have unique features to attack . Folic acid synthesis (bacteria make their own, animals.
