Abstract : The research performed during the grant period was destined to establish the basement for the future development of the project. Experiments were conducted in three different lines: I. Incorporation of tritium labelled thymidine in living animals (Gryllus argentinus); II. Culturing isolated testicular tubes of the same species in view of using inhibitors of the deoxiribonucleic acid and of protein synthesis; III. Irradiation of specimens at the larval stage (prior to the beginning of meiotic prophase) and electron microscope examination of the cells fixed at varied intervals of time after irradiation.
