FIGURE 6.

Quantitative estimates of intracapsid viscosities. A, log-log presentation of MRV transcription data from Fig. 1A. Data for both glycerol and sucrose were combined for this presentation. Only data for solution viscosities above the critical concentration (0.8 cP) are shown; data for lower viscosities have been omitted. Log₁₀ values of transcript yields are plotted versus log₁₀ values of either solution viscosity (filled circles) or the cube of solution viscosity as described in the text (open circles) (linear curve fits, r² = 0.97). B, Same data as in Fig. 1B (right) but plotted relative to the cube of solution viscosity, based on the results shown in A. Only data for external viscosities above the critical concentration are shown. C, same type of log-log presentation as in A, but in this case for RRV transcription data from Fig. 4A. Log₁₀ values of transcript yields are plotted versus log₁₀ values of either solution viscosity (filled circles) or the square of solution viscosity as described in the text (open circles) (linear curve fits, r² = 0.90).
