The enzyme-free toehold-mediated strand displacement reaction has shown potential for building programmable DNA circuits, biosensors, molecular machines and chemical reaction networks. Here we report a simple colorimetric method using gold nanoparticles as signal generators for the real-time detection of the product of the strand displacement cascade. During the process the assembled gold nanop...
Gene damage in cultured human alveolar (L-132) cells induced by exposure to dimethylarsinic acid (DMAA), a major metabolite of inorganic arsenics in mammals, was studied. DNA single-strand breaks and DNA-protein cross-links were induced by the treatment of L-132 cells with 10 mM DMAA. These kinds of damage appeared at 8 hr after start of exposure to DMAA. As regards DNA-protein cross-links, the...
Introduction: Passage of ionizing radiation through the organs of living creatures develops clusters of damaged nucleotides inside the DNA rounds. 192Ir Gamma source is one of the most widely used sources in brachytherapy of cervical and prostate cancer. Thus, in this research, we investigated the flux of photons and its resulting secondary electrons, the single-strand break (S...
dna polymorphism within diacylglycerol transferase 2 (dgat2) / monoacyl glycerol transferases 2 (mogat2), leptin and butyrophilin genes were analysed using pcr-sscp in murrah buffalo. the single strand conformation polymorphism (sscp) analysis of amplified gene fragment in exon 5 of mogat2, exon 3 of leptin and intron 1 of butyrophilin gene revealed different patterns. a, b and c showed the fol...
Integrons play a major role in the dissemination of antibiotic resistance genes among Gram-negative pathogens. Integron gene cassettes form circular intermediates carrying a recombination site, attC, and insert into an integron platform at a second site, attI, in a reaction catalyzed by an integron-specific integrase IntI. The IntI1 integron integrase preferentially binds to the 'bottom strand'...
