Replication and recombination in ligase-deficient rII bacteriophage T4D.
Deoxyribonucleic acid replication and genetic recombination were investigated after infection of Escherichia coli with ligase-deficient rII bacteriophage T4D. The major observations are: (i) deoxyribonucleic acid synthesis is discontinuous, (ii) the discontinuities are more slowly repaired than in wild-type infection, (iii) host ligase is required for viability, and (iv) genetic recombination is increased.
