Abstract
Plasmolysed chloramphenicol-treated Escherichia coli cells carrying the colicinogenic factor E1 utilize deoxynucleoside triphosphates for the semi-conservative synthesis of Col E1 DNA. Col E1 DNA replication in plasmolysed cells can be dissociated into two temporally separated processes: (a) a rifampicin-sensitive RNA synthesis, which is stimulated by adenosine 3':5'-monophosphate (cyclic AMP) and requires all four ribonucleoside triphosphates and (b) an ATP-dependent DNA synthesis, which is inhibited by arabinosylnucleoside triphosphates and sulfhydryl-blocking reagents. Thes two processes exhibit different sensitivities to inhibition by polyamines and actinomycin D.Keywords
