Journal ArticleDOI
Co-operative non-enzymic base recognition. I. Thermodynamics of the helix-coil transition of oligoriboadenylic acids at ACIDIC PH.
Manfred Eigen,Dietmar Porschke +1 more
TL;DR: Results show that the stacking between adjacent base pairs is the main source of stabilisation and that the enthalpy of base pairing in the co-operative model is mainly given by the ent Halpy of stacking.
Journal ArticleDOI
Interactions between the quaternary structure of the globin and the spin state of the heme in ferric mixed spin derivatives of hemoglobin.

Journal ArticleDOI
Mg2+-dependent conformational changes in the hammerhead ribozyme
TL;DR: This approach provides a first set of data describing a Mg2+ binding topography to hammerhead RNA molecules and should be useful for the analysis of other RNA molecules.
Journal ArticleDOI
Persistence length and bending dynamics of DNA from electrooptical measurements at high salt concentrations.
TL;DR: The data indicate that formation of individual, sequence-directed structures of DNA fragments is favoured under physiological salt conditions, with large deviations from the model average than corresponding time constants measured previously at low salt.
Journal ArticleDOI
Orientation relaxation of DNA restriction fragments and the internal mobility of the double helix.
TL;DR: It is suggested that electric fields induce stretching of the DNA fragments from a weakly bent to a more straight form and that the fast component reflects the internal mobility of theDNA chain.
