[Frequency and gradient dispersion of viscosity of dna solutions].

Gradual and frequential dispersion of the viscosity of DNA solution in cattle splin was studied. Zimm--Crothers rotational viscosimeter was used for determining gradient relationship of viscosity eta (g). To determine frequential dispersion of viscosity a magnetelecttric vibrational viscosimeter with the working range of 16-100 Hz was produced. It was found that gradient relationship of specific viscosity coincides within the measuring error with the frequential relationship of actual component of specific viscosity at dynamic measurements. The influence of the alternating force with the frequency f is equivalent to the effect of stationary applied force producing the gradient g=k with f, where k=3,2 plus or minus 0,4.
