The cancer chemotherapy drug bleomycin (BLM) is a potent inducer of genetic damage in a wide variety of assays. The radioprotectors cysteamine (CSM) and WR-1065 have been shown in previous studies to potentiate the induction of micronuclei and chromosome aberrations by BLM in Go human lymphocytes. B
A haploid strain of Asp. nidulans with a chromosome segment in duplicate (one in normal position on chromosome I, one translocated to chromosome II) shows mitotic recombination, mostly by conversion, in adE in a frequency slightly higher than in the equivalent diploid. A method has been devised, usi
Yeast cultures progressing from the exponential to the stationary phase of growth showed changes in cell sensitivity to physical agents such as UV light, heat shock at 52 degrees C and the chemical mutagens ethyl methane sulphonate, nitrous acid and mitomycin C.

## Abstract An aqueousβalcoholic extract of yeast (PCO) was found to inhibit mitoses in Sarcoma 180, Krebsβ2 ascites carcinoma, and the Lβ1210 leukemia in vitro. Contrariwise, PCO did not inhibit, and in some experiments even stimulated, the mitoses in the following normal cells in vitro: Lβ929 fib
The effect of UV irradiation on the survival, inter- and intragenic mitotic recombination of 3 diploid UV sensitive Saccharomyces mutants was studied and compared with the wild type RAD. These strains, homozygous for either the RAD, r1s rad 9-4, or rad 2-20 gene, have DRF values for survival of 1:1.
