Biology 3593B Study Guide - Quiz Guide: Dapi, Antimicrobial Resistance, Doubling Time
Document Summary
Non-exponential bacteria comparable to eukaryotic: phase= period . G1 = b period= growth in mass. S (+g2) = c = dna synthesis: plus, necessary decatenation post-replication, any subsequent growth hence no g2 equivalent. M (+c) = d - dna partition: d also includes cytoplasm partitioning cytokinesis. Simultaneous replication rounds possible: exponential: no b period c periods overlap, generation time in optimal medium < time to replicate whole genome, e. coli good medium 40 mins doubling time; can be 20. Less prominent quiescence: multicellular eukaryotes key in adult only epithelial progenitors truly proliferative rapid replacement, quiescent persister" bacteria only subpopulation of culture although tb antibiotic resistance. Not direct parallels: g2 part of c; cytokinesis d. E. coli 4. 7mb chromosome 1. 5mm uncompacted: min. Dna / cell exponential multiple chromosome: cell dimensions 1 x 0. 5 microns > 1000 mismatch, dapi nucleoid = 50-70% cell, also localised => scaffold.
