Abstract

Gamma ray-induced mutants of Chinese hamster ovary cells lacking dihydrofolate reductase activity were screened for DNA sequence changes at the locus specifying this activity by using a cloned cDNA probe. Two of nine mutants screened displayed an altered restriction fragment pattern suggesting the occurrence of DNA deletions or rearrangements.
