Metabolically Generated Free Radicals from Many Types of Chemical Carcinogens and Binding of the Rapyrene in which no diol-epoxide formation is expected were found to be activated to reactive free radicals. These findings suggest that the metabolically formed free radicals are important in chemical carcinogenesis.

Biological Effects of Specific Hydrocarbon-DNA Reactions,icity of the .- and .-diolepoxides of benzo(a)pyrene revealed differences in absolute efficiency reminiscent of data obtained with methylating agents which gave different DNA alkylation products. The significance of these data to the role of mutation in cancer initiation is discussed

The Effect of Base Modification on Fidelity in Transcription,possible tautomeric shift with C, the orientation of the substituent plays a major role in determining fidelity. Thus N.-methoxy C acts only as U; N.-hydroxy C, N.-MeC, and N.-MeG act ambiguously; and N.-acetyl C base-pairs only with G. Three different substituents on the N. of A did not affect A·U pairing, indicating an anti conformation.

On Euler Buckling and Snap-Through,tereochemical factors are also critically important determinants of biological activity. Several hydrocarbons have now been tested, either directly or indirectly, and have been found to meet the predictions of the theory.

Business Cycles: Discrete Time,sence of even weak nucleophiles in the incubation. In contrast, products of 7,8-dihydro- 7,8-dihydroxybenzo(a)pyrene seem to be trapped primarily by enzyme- mediated glutathione conjugation. Our results underline the physiological importance of the nuclear envelope in the final activation of benzo(a)- pyrene to DNA-binding products.
