Transformation by hamster polyomavirus: identification and functional analysis of the early genes.

abstract：:The insertion of a particular phi X DNA sequence in the plasmid pACYC177 strongly decreased the capacity of Escherichia coli cells containing such a plasmid to propagate bacteriophage phi X174. The smallest DNA sequence tested that showed the effect was the HindII fragment R4. This fragment does not code for a complet...
