Values in A, B and D are mean ± SD ( n = 6). The western blot shown in (C) is a representative example of four independent experiments. WebDNA adduct. A metabolite of benzo [ a ]pyrene forms an intercalated DNA adduct, at center. In molecular genetics, a DNA adduct is a segment of DNA bound to a cancer-causing chemical. This process could lead to the development of cancerous cells, or carcinogenesis. DNA adducts in scientific experiments are used as biomarkers of exposure.
WebJan 18, 2002 · A possible scenario for BaP bypass might be the following: when the replicative DNA Pol III encounters the BaP adduct in the present sequence context, it has the capacity to insert A or C opposite the adduct. Two kinds of lesion termini are thus generated: the C- and A-lesion termini . WebGo to BAP_Compass r/BAP ...
