Beschreibung
Zusammenfassung:	The present invention provides compositions and methods for controlling the copy number for a broad range of plasmids and uses thereof. Disclosed is a host cell for conditional control of copy number of a plasmid, which host cell comprises a poly(A) polymerase gene that is operably joined to a conditionally inducible promoter, and a method for cloning and stably maintaining a DNA sequence encoding a heterologous polypeptide in the host cell.
