Effect of defects on thermal denaturation of DNA Oligomers
arXiv:cond-mat/0105054 · doi:10.1103/PhysRevE.64.042901
Abstract
The effect of defects on the melting profile of short heterogeneous DNA chains are calculated using the Peyrard-Bishop Hamiltonian. The on-site potential on a defect site is represented by a potential which has only the short-range repulsion and the flat part without well of the Morse potential. The stacking energy between the two neigbouring pairs involving a defect site is also modified. The results are found to be in good agreement with the experiments.
