紫外线作用于细胞后,损伤DNA并进行非程序性DNA合成(unscheduled DNA synthesis,简称UDS),所以非程序性DNA合成可作为DNA损伤的观察指标。化学致癌物也损伤DNA,近年来以体外培养的动物或人的细胞的非程序性DNA合成作为化学致癌物的生物测定法常有报道。我们曾从24种维
Ultraviolet rays act on the cells, damaging the DNA and performing unscheduled DNA synthesis (UDS), so non-programmed DNA synthesis can be used as an indicator of DNA damage. Chemical carcinogens also damage DNA. In recent years, bioassays using non-programmatic DNA synthesis of animal or human cells cultured in vitro as chemical carcinogens have been frequently reported. We used to have 24 dimensions
