The changes in DNA base sequence induced in the lambda cI gene in an E. coli lysogen have been determined following mutagenesis by three acridine derivatives: 9-aminoacridine and proflavin, which bind reversibly to DNA; and ICR-191, which attaches covalently to DNA through a half-mustard group. For
In this paper are studied in E. coli K12 the influence of the bacterial Rec and phage mu Red recombination systems on the rescue of the O plus gene from the prophage by a superinfecting O minus phage, UV irradiated or not. In the absence of UV irradiation the Red system produces more recombinants th
