## Synopsis Studies were made of the influence of hydrostatic pressure on the helix-coil transitions of poly(A + U) and poly(A + 2U). The results were analyzed by a thermodynamic treatment which emphasized the cooperative aspect of the transitions. The helix-to-coil volume changes were found to be

Studies of the helix-to-coil transition in dilute solutions of poly-L-lysine, dissolved in mixtures of water and methanol (MeOH), have been carried under shear flow using flow birefringence and modulated polarimetry. The fraction of helical conformations in a given solution remains independent of sh
## Abstract The effect of magnesium ions on the parameters of the DNA helixβcoil transition has been studied for the concentration range 10^β6^β10^β1^__M__ at the ionic strengths of 10^β3^__M__ Na^+^. Special attention has been given to the region of low ion concentrations and to the effect of poly
