Yet, the nature and relative rates of the reactions involving active oxygen species make it difficult to ascertain, in each particular situation, what reactants may act as the predominant genotoxicant and what DNA repair mechanisms may ensue.

Most recently, in order to separate the potential biological effects of each derivative, defined oligonucleotide sequences containing a single adduct have been synthesized and used to study both replication and mutation. These defined oligomers have also been of grea

Cyber-Salvation: Body in Virtual Skies MNNG or nitrosoureas (Day, ., 1980a,b; Erickson, 1980a,b; Scudiero, ., 1984 a,b; Gibson, ., 1986). The results obtained in cell culture are clear-cut; for example, with MNNG as the damaging agent, the inactivation slopes of survival curves of Mer. cells are up to 50 fold steeper than are those of M

Ove Jakobsen,Vivi M. L. Storslettenr εCdR. Molar ratios of oxetG/εCdR and oxetG/εAdR in DNA were about 3 0 and 80, respectively, in these three organs. In contrast, εAdR and εCdR were not detected (detection limit, 2 5 fmoles/mg DNA) in the kidney of group I nor in the liver from group II rats. These findings are discussed in relatio

Luk Bouckaert,Knut J. Ims,Peter Ronaon analyses supplied support for the idea that proneness to mutation is passed on to daughter cells (Maher, ., 1988). As another parallel between bacteria and mammalian cells DNA damage causes reinitiation of replication (Kogoma, ., 1979) which in mammalian cells is observed as gene amplification (L
