Genetic Changes Induced by Exposure to Nitrogen Mustard and Their Inheritance I N Paramecium
N RECENT years chemical induction of mutation has assumed considerable I importance in experimental genetics, as evidenced particularly by the work of AUERBACH and ROBSON (1944, 1946, 1947a, 1947b), AUERBACH (1949a, b) and others. These workers, investigating mustard gases and related compounds found them to be potent mutagens in various organisms. One of the compounds shown by AUERBACH and ROB...
متن کاملInheritance of Mutational Changes Induced by Radiation in Paramecium Aurelia.
N a previous paper KIMBALL (1949) has described the induction by radiation I of changes in vigor in Paramecium aurelia which first expressed themselves in the exautogamous progeny of rayed animals. In that paper, it was assumed that the changes were due to mutations in the micronucleus. This paper will present the genetic evidence which bears on this assumption. The radiation studies suggested ...
متن کاملSex, Sex Inheritance and Sex Determination in Paramecium Aurelia.
those produced by x-irradiation, the above result and further experiments producing mutations with neutrons may lead to new conclusions regarding the interaction of radiation ions with genes and hence of the size and structure of the gene. It is interesting to note that the ratio of effectiveness (5 or 6 to 1) for the effects on mature sperm of neutron as compared with x-irradiation is comparab...

متن کاملSpontaneous Mutations Affecting the Killer Character in Paramecium Aurelia, Variety 4.
ILLER paramecia release into the medium in which they live a poison, paraK mecin, to which they are resistant but which kills other sensitive paramecia (SONNEBORN 1939, 1943). Two spontaneous mutations of the killer character are analyzed in this paper. One of these proves to be a mutation of kappa, the cytoplasmic genetic particle determining the killer trait (SONNEBORN 1946) ; the other is a ...
