돌연변이율을 증가시키는 기능이 결여된 플라스미드 pKM101의 분리 및 그 특성에 관한 연구Isolation and characterization of plasmid pKM 101 mutants deficient in their ability to enhance mutagenesis
As preliminaries for the study of Plasmid pKM101 functions and their interaction with the host DNA repair genes, seven mutants of pKM101, visualized on tetrazolium-galactose plates, deficient in their abitity to enhance mutagenesis were isolated and partially characterized. They all have altered functions not only for mutagenesis against MMS and 4-NQO but for the spontaneous reversion of host cell.
