Dependence of the RNA secondary structure from the energy model — •Bernd Burghardt and Alexander K. Hartmann — Institut für Theoretische Physik, Universität Göttingen

In the literature mainly two different types of energy models are considered for RNA secondary structures: On the one hand side every paired base pair is assigned an energy, on the other hand only so called stacked base pairs, e.g. two or more consecutive base pairs, are assigned an energy. We examined a model that uses both types of energy contributions, and therefore we were able to study the transition from one type of the above mentioned energy models to the other one. We have done numerical studies on statistical quantities, where we used algorithms that are able to calculate the partition function and the ground-state energy exactly in polynomial time.
