Theoretical investigation of DNA oligomer systems. Modification of the hydrogen atoms transfer in a base pair due to time-dependent interaction with stacked base pairs

The hydrogen atoms transfer process in a generic polynucleotide of DNA has been studied with a theoretical approach. The role of time-dependent interaction among these processes on different base pairs has been analysed. An Hamiltonian with a time-dependent coupling among the nearest neighbor base pairs has been utilised. This general model evidences a complete hydrogen atoms transfer in a base pair with at least one equal nearest neighbor base pair along the chains. © 2006 Elsevier B.V. All rights reserved.
