Recombination-deficient Mutant of Salmonella typhimurium1

AUTOR(ES)
RESUMO

A recombination-deficient (Rec−) ultraviolet-sensitive mutant of Salmonella typhimurium was isolated. The mutant grows more slowly than the wild-type strain and degrades its deoxyribonucleic acid extensively both during normal growth and after ultraviolet irradiation. Evidence is presented that a growing Rec− population consists of two types of cells, one which can divide and one which cannot.
