Large-scale opening of A + T rich regions within supercoiled DNA molecules is suppressed by salt.

Large-scale cooperative helix opening has been previously observed in A + T rich sequences contained in supercoiled DNA molecules at elevated temperatures. Since it is well known that helix melting of linear DNA is suppressed by addition of salt, we have investigated the effects of added salts on op...
