Document Summary
Minimum size due to genome, protein, ribosome requirements, etc. Greater rate of nutrient/waste exchange, can support quick growth, fast evolution. Use of cations to shield negative charge on sugar phosphate backbone. No histone protein (like those in archaea and eukaryotes) Builds chain that pushes two plasmids to either end. All layers surrounding the cytoplasm (includes membrane, wall, outer membrane) Glycerol attached by ester linkage to 2 fatty acid tail.

L-alanine is more common, but d-alanine is found in cell wall. Without a cell wall, cell can"t resist pressure changes. Antibiotic resistance created beta lactamase which could destroy ring. Lps in gram negative cells can be harmful. Lipid a causes immune system to fire off. Goes through protein tube directly into another cell.
