Document Summary
From viruses (transduction); environment (transformation); or another cell (conjugation) Glycerol to straight- chain fatty acids via ester. Glycerol to straight chain fatty acids via ester. B no histones, simple rna polymerase, formylmethioine, different dna polymerase, translation stopped by certain antibiotics, peptidoglycan/muramic wall. A ether glyceride, flagella is bacteria-like but different in composition, no organelles. E nuclear envelope, undulate flagella, cellulose/chitin wall. Feature of prokarya unicellular assimilative versatile conservative small numerous omnipresent diverse promiscuous. Some have rudimentary divison of labour: heterocyst but no complex differentiation. Use extracellular enzymes to break down polymers, monomers transported in, large fraction of bacteria genome encodes transporters. Can use just about anything as an electron donor substrate. Even though substrates are diverse, all are transformed by similar processes and similar intermediates. Inertial resistance: pressure drag; viscous resistance: fluid friction drag. Ratio of inertial to viscuous resistance is reynold"s number: (d/v) vl = re. D density v viscosity v velocity l length.
