Conjugation in Escherichia coli: recombination events in terminal regions of transferred deoxyribonucleic acid.

abstract：:Host range mutants of phage T1 (T1h), which productively infected tonB mutants of Escherichia coli, were isolated. The phage mutants were inactivated by isolated outer membranes of E. coli in contrast to the wild-type phage, which only adsorbed reversibly. For the infection process, the tonB function is apparently onl...
