Molecular Energetics of Clustered Damage Sites in DNA


EMSL Project ID
3687

Abstract

The objective of this project is to use state-of-the-art computational chemistry models to obtain molecular insight and characterization of the structure, energetics, and spectroscopy of singly and multiply damaged (clustered) DNA sites. This research will provide a fundamental, quantitative, first-principles basis in DOE efforts to assess whether endogenous processes and ionizing radiation produce qualitatively and quantitatively different kinds of damage. The project specific aims are (1) to construct computational models of DNA lesions representative of those formed by endogenous processes and by low- and high Linear Energy Transfer (LET) radiation and (2) to computationally characterize the molecular-level properties of model singly and multiply damaged DNA sites.
