Conservative estimates for the upper and lower bounds to the globule-torus transition region are found. These are then used to demonstrate that the polymer globule undergoes considerable changes to its overall morphology and internal packing arrangements for stiffness values outside this transition region. Using a variety of methods we characterize these globular structures as stiffness is varied.Keywords: Computer simulation; Condensation; DNA; Heavy ions; Homopolymerization; Morphology; Phase transitions; Positive ions; Solvents; Stiffness; Temperature measurement; Brownian dynamics simulation; DNA condensation; Semiflexible polymer; Toroids; Biopolymers Brownian dynamics simulation; DNA condensation; Phase transition; Semiflexible polymer; Toroids200410.1016/j.physa.2004.03.0392015-12-11
