Garrison-Morton 254; Norman 326. RARE OFFPRINT of "a paper of fundamental importance in molecular biology" (Garrison & Morton). PRESENTATION COPY, the upper wrapper indistinctly inscribed by Timofeeff-Ressovsky. "'Ueber die Natur der Genmutation und der Genstruktur'" (often referred to as "the green paper" after the color of its wrappers, or the "Dreimänner" paper after the number of its authors) is divided into four sections. The first, by Timofeeff-Ressovsky, describes the mutagenic effects of x-rays and gamma rays on Drosophila melanogaster; the second part, by Zimmer, analyzes Timofeeff-Ressovsky's results theoretically. The third and most remarkable section, by Delbrück, puts forth a model of genetic mutation based on atomic physics that "shows the maturity, judgment and breadth of knowledge of someone who had been in the field for years . . . its carefully worded predictions have stood the test of time" (Perutz, Physics and the Riddle of Life, p. 557). - Visit our website to see more images!
