Ade-H and ade-I are two auxotrophic mutants of Chinese hamster ovary (CHO-K1) cells which specifically require adenine as the purine source to grow. The enzymatic defects of these mutants were examined in cell-free extracts. B was found that ade-H did not have any detectable adenylosuccinate synthet

## Abstract A mutant (A204) of Chinese hamster ovary cells (CHO‐K1), which is deficient in dihydroorotate (DHO) dehydrogenase (E.C. 1.3.3.1) activity, has been isolated by a replica plating procedure. The mutant does not show a requirement for exogenously added pyrimidines. Examination of intact ce
