| Popis: | The dose-frequency relationship for 2 types of mutation, fractional- and whole-body, was obtained using soft X-rays on Drosophila melanogaster . At low doses ( e.g. 400 R to 1440 R) more fractionals were induced than whole-body changes, whereas at high doses ( e.g. 3000 R) the reverse relationship was observed. These results are in agreement with those of other investigations involving Drosophila and yeast. The origin of these mutations is discussed in relation to the strandedness of the DNA molecule of the gene. |
