Research paper

Mutants of Drosophila melanogaster that are sensitive to chemical mutagens were analyzed for sensitivity to X-rays and for the capacity to repair single-strand DNA breaks induced by X-rays. Analysis of X-ray sensitivity demonstrated that 74% of the mutants assayed display some X-ray sensitivity, with 75% of the sensitive lines being extremely sensitive. Repair of single-strand breaks was assayed after both high and low doses of irradiation in order to permit detection of repair over a wide range of damage. The results of this investigation fail to show a correlation between X-ray sensitivity and this particular repair process. Repair of single-strand breaks is therefore mediated by repair processes unrelated to those that are disrupted in the current mutant collection.
