Radiation and biophysical studies on cells and viruses. Progress report 1 July 1977--30 June 1978

Studies on genetic structure included arrangement of interphase and mitotic chromosomes, nucleoproteins, and DNA. Studies on analysis of sensitive sites by particle beam irradiation included location of cellular sites for mutation induction and cell transformation. Studies on radiation damage and repair and radiation as an investigative tool included damage to nuclear proteins and other model systems; detection and quantitation of cell surface antigens; interaction of hyperthermia and irradiation; radioinduced cell transformation alkaline elution studies of damage and repair; and low dose, low LET lethality
