title: DNA injection and genetic recombination of alkylated bacteriophage T7 in the presence of nalidixic acid.
abstract: Marker rescue experiments with alkylated T7 bacteriophage carried out in the presence and in the absence of nalidixic acid suggest that the gradient in rescue is due to two alkylation-induced causes: a DNA injection defect and an interference with DNA synthesis.
