A method of directly sequencing for double strandDNA by using Tc resistance gene of pBR322 as templateand oligonucleotide 5’-GGCCCTTTCGTCTTC-3’as primerwhich is located on the adjacent to the EcoRI sitewith the coun...
Epidemiological studies have shown thatarsenic compounds cause lung and skin cancerin human.Studies of effect of arsenic onDNA were still deficient.The results of thestudies were unreliable.It makes more diff-iculty t...
DNA double strand breaks (dsb) induced by Coγ-rays were studied in Chinese hamster fib-rolast cell line (CHL) by means of a sensitivefluorometric techniqe.DNA strand breaks due toirradiation of cell samples from 0 to...
We have selected four mouse cell mutantshypersensitive to the lethal effect ofionizing radiation.They show cross-sensitivity to bleomycin and otherchemicals but not to ultraviolet light.
A preliminary study on application of Pluorometric Analysis ofDNA Unwinding(FADU)to the detection of DNA strand breaksinduced by indirect environmental mutagen benzo(a)pyrene(BaP)was conducted.The results showed...
