Abstract
The torsional and bending rigidities of Z-form DNA have been studied by nanosecond fluorescence anisotropy measurements of intercalated ethidium. The results suggested that Z-form DNA was considerably more flexible than B-form DNA. We have investigated the temperature dependence of the rigidity of B- and Z-form DNA and found that the temperature dependence of the torsional rigidity of Z-form DNA was remarkably lower than that of B-form DNA.
