Figure 1

Semilogarithmic plots of the dependence of the fractional decay of the birefringence, Δn/n, of the 199-bp SV40 fragment on the time elapsed after removal of the electric field, in μs. A, Decay observed in buffer B, without Mg2+ ions, τ = 3.74 μs; B, decay observed in buffer F, containing 0.1 mM Mg2+ ions, τ = 2.83 μs.
