On Euler Buckling and Snap-Through,part of a bay-region of a carcinogenic polycyclic aromatic hydrocarbon. In general, predicted chemical reactivity for positional isomers of benzo-ring diol epoxides of individual hydrocarbons has been paralleled by their respective mutagenicity and/or tumorigenicity. Although relative reactivity of

J. E. Macías,M. G. Clerc,C. Falcónter embryo cells treated with the hydrocarbon contain adducts arising from the reactions with the nucleic acid of both the ‘bay- region’ .-3,4-diol-1,2-epoxide and the non-‘bay-region’ .-8,9- diol-10,11-epoxide. However, only the 8,9-diol-10,11-epoxide appears to be involved in the reaction of the h

Z. Liu,F. Leo,S. Coulibaly,M. Takiderivatives, acetylaminofluorene and naphthylamines have been found to be easily converted to free radicals after being activated to the proximate forms. These free radicals were sufficiently reactive to bind covalently with nucleic acid bases. Anthanthrene which lacks bay region and 10-aza-benzo[a)

Business Cycles: Discrete Time,ar orbital calculations. Of particular interest is the degree to which epoxide ring opening may be facilitated by either or both of two special factors: (1) The proximity, in the molecule, of a double bond, and (2) intramolecular hydrogen bonding between an appropriately oriented hydroxyl group and

The cell-mediated mutation system was used to compare the mutagenic efficiency of a series of parent hydrocarbons. Quantitative studies of the mutagen

When normal hydrogen bonding is blocked by a substituent, total ambiguity results with transcription continuing beyond the modified nucleotide. Examples are 3-MeC, 3-MeU, 1-MeA and O.-MeU.
