In our model,DNA chain is regarded as freely connecting segments with a bead tethered to the end of the chain.

Studies on the DNA strand breakage as biomarker of exposure to aldehyde pollutants;

Study in vitro on the activity of poly(ADP-ribose)polymerase(PARP)and DNA strand breakage induced by nickel;

DNA strand breakage of human hepatoma cells induced by γ-ray measured using the Comet Assay;

5) in Beijing on micronucleus formation of Balb/c 3T3 cell and DNA strand breaks, were inspected using cytochalasin B-blocked test and single cell electrophoresis method; and their effects on gap junction intercellular communication (GJIC) of Balb/c 3T3 cells were observed through scrape-loading/dye transfer (SL/DT) technique.

The results showed that the deoxyguanosine modification and DNA strand breaks upon the concentration of peroxynitrite.

Objective To investigate DNA strand breaks and micronuclei induced by sodium pentachlorophen (Na-PCP) in different phases and different dosages in vivo.

Factors influencing the stability of triplex DNA;

DNA triple-helix formation is of great potential including selective control of gene expression, site-directed mutagenesis, gene repair, in situ chromosome labelling and other molecular diagnostics, thus the antigene strategy based on triplex DNA offers new therapeutic applications.
