title: DNA repair in Syrian hamster embryo cells treated with 7,12-dimethylbenz[a]anthracene and its weakly carcinogenic 5-fluoro analog.
abstract: The postreplication repair capacity of Syrian hamster embryo cells in culture was determined after treatment with the potent carcinogen 7,12-dimethylbenz[a]anthracene (DMBA) and its weakly carcinogenic analog 5-F-DMBA. The size and amount of daughter DNA sedimenting as high-molecular-weight DNA were found to be less in the DMBA treated cells than in the 5-F-DMBA-treated cells. This difference probably depends upon the types of adducts entering DNA replication.
