Abstract
Catenated deoxyribonucleic acid molecules of colicin factor E1 (Col E1) were found with nearly equal frequency in minicells derived from Escherichia coli strain P678-54 recA+ (Col E1) and P678-54 recA− (Col E1). The result suggests that the recombination function controlled by the recA gene does not influence the formation of catenated Col E1.
