Free-Radical Yields in Proton Irradiation of Oriented DNA: Relationship to Energy Transfer Along DNA energy and charge transfer along DNA chains could be very important in lesion development. This paper describes investigations of these phenomena through model calculations and measurements of radical yields in oriented DNA exposed to proton irradiation.

Biological Action of Single Heavy Ions on Individual Yeast Cellsuter aided image analysis. The results show that the biological action depends on atomic number and specific energy of the impinging heavy ions. A comparison with the results of a model calculation is presented.

Also certain physiological conditions have been known to induce DNA damage e.g. thymine starvation of thymine auxotrophs and heat shock (Friedberg, 1985; Smith and Burton, 1965; Anathaswamy and Eisenstark, 1976; Smith, 1988; Smith, 1966; Lindahl, 1982; Johansen, et al., 1971).

Relativistic Kinetic Theory for Matter,s DNA solutions, radiolysis of water produces OH radicals which react with DNA bases and sugar residues; hydrogen atom abstraction from the sugar moieties produces radicals which ultimately give rise to strand scission. In the case of low LET radiation (e.g. γ-irradiation), DNA damage caused by OH-
