title: Nuclear disruption after infection of Escherichia coli with a bacteriophage T4 mutant unable to induce endonuclease II.
abstract: Nuclear disruption after infection of Escherichia coli with a bacteriophage T4 mutant deficient in the ability to induce endonuclease II indicates that either (i) the endonuclease II-catalyzed reaction is not the first step in host deoxyribonucleic acid (DNA) breakdown or (ii) nuclear disruption is independent of nucleolytic cleavage of the host chromosome. M-band analysis demonstrates that the host DNA remains membrane-bound after infection with either an endonuclease II-deficient mutant or T4 phage ghosts.
