title: Pattern of replication of a colicin factor during the cell cycle of Escherichia coli.
abstract: The ColBM, trp, lac episome was transferred to a lacZ derivative of Escherichia coli B/r, and the manner of replication of this colicinogenic factor was followed through the cell cycle. The results suggest a pattern of replication not connected with any particular stage in the cell cycle.
