Figure 12A-3 Sedimentation Coefficients and Densities of Organelles, Macro molecules, and Viruses. A particle's 1.9 sedimentation coefficient, expressed in Svedberg units (S) indicates how rapidly it DNA sediments when subjected to a centrifugal Glycogen force. A particle's density (expressed in g/cm) determines how far it will move during Ribosomes and polysomes equilibrium density centrifugation Soluble protei Peroxisome Nuclei iruses Lysosomes Mitochondria Chloroplasts 1001000104 105 Sedimentation coefficient (S) (continued)
