Biological effects of DNA repair, including mutagenesis: Progress report for the period June 1, 1987-March 31, 1988

Technical Report ·
OSTI ID:5168958

A study shows the effects of gamma radiation on inducing gross rearrangements in the DNA of mammalian cells in culture is described. A line of CHO cells, K1-X3/5, in which most or all of the single copy of the endogenous hprt gene on the X chromosome has been deleted was used. Various transformed cell lines have been made in which a single copy of the E. coli gpt gene has been stably incorporated into the chromosome. These cell were irradiated with gamma rays, and gpt mutants isolated by the same procedures routinely used to isolate hprt mutants. Those mutants that contain DNA with altered Southern blots are assumed to have gross rearrangements in the DNA.
