Abstract excerpt
The thymidine kinase locus (tk) has been utilised as the target locus to measure the induced mutation frequency following X-irradiation in the X-ray-sensitive xrs5 mutant and its parent CHO K1 line of Chinese hamster cells. Mutations to tk- cells were measured by plating cells in selective medium containing trifluorothymidine after a post-irradiation expression time of 4 days. Our results show that the mutation...
