The Survival of Haploid and Diploid Vertebrate Cells after Treatment with Mutagens,ates in bacteria, therefore, the proportion of diploid cells which survive mutagen treatment should be at least 10. times that of haploid cells. A haploid-diploid comparison should, in fact, be a test for the mutagenic nature of a compound.

Gas Chromatographic Analysis of PCBsase in the specific activity of these enzymes during cellular aging (1). Since these enzymes are typically marker enzymes for lysosomes, the findings implied that older cells contained more lysosomes, a conclusion that has since been documented by electron microscopic studies in our lab and by other

The age effects have been observed both in man and in other mammals. The normal human m
