Segregation into and replication of plasmid deoxyribonucleic acid in chromosomeless segregants of Escherichia coli

J Inselburg. J Bacteriol. 1970 Jun.

Abstract

The progeny cells of Escherichia coli strain P678-54, which normally do not contain deoxyribonucleic acid (DNA), were found to carry DNA when the parental cell carried colicin factor E1 (Col E1). The DNA found in the normally DNA-less segregants was shown to be Col E1 DNA, which is present primarily as a covalently closed circular molecule that can undergo more than one complete cycle of replication.
