This is the final report of a study conducted at the Eleanor Roosevelt Institute for Cancer Research, Inc. This study looked at mutagenesis as a measurement of the effects of chemical agents. Topics discussed in this report include: development of a new theory for the role of lipids and lipoproteins in the interactions of macromolecules; the action of caffeine in synergizing mutagenesis of agents like ionizing radiation by inhibition of cellular repair processes which was incorporated into a rapid procedure for detection of mutagenicity with high sensitivity; quantitative theoretical analysis of the mutagenesis process in cells exposed to physical and chemical mutagenic agents; theoretical analysis was developed leading to the conclusion that the visible chromosomal lesions described will also include a significant proportion of point mutations; application of this methodology for meaningful measurement of mutagenesis to study the effects of chemical agents was begun; and investigation of the cell cytoskeleton`s effect of genome exposure operating in the course of the differentiation process
