✦ Synopsis

The time required for the completion of the process of strand separation ill X bacteriophage DNA preparations exposed to strongly alkaline conditions in aqueous glycerol solutions was directly proportional to the viscosity of the solvent. This finding s u p ports the idea that the rate-limiting step in the denaturation of high molecular weight DNA is the uncoiling of the strands and in the course of this uncoiling the forces arising from electrostatic and entropic factors must overcome the hydrodynamic viacotis drag of the solvent resisting the translation of the polynucleotide strands.

The rate of double helix formation by single stranded Poly A plus Poly U, Poly I plus Poly C, Poly G plus Poly C, and T 2 DNA has been investigated as a function of both the length of the reacting strands and temperature. The length dependence of the rate is found to be independent of temperature. A
