[Bacteriophages T3 and T7: transcription-dependent mechanism of phage DNA transport into the cell during infection].

The mechanism by which bacteriophage T3 DNA is transported into the E. coli cell during infection was studied. The data obtained testify that bacteriophage T3, similarly to what we have earlier found for bacteriophage T7, introduces its DNA into the infected cell is a transcription-dependent way. A detailed discussion is presented on the occurrence of the transcription-coupled transport of viral DNA into the infected cell and on a number of general issues concerning the transport functions of template-directed enzymes.
