EXPLANATION FOR LIMITATION OF POPULATIONS OF ESCHERICHIA COLI IN BROTH CULTURES.

abstract：:The bacteriophage Mu genome contains a centrally located strong gyrase site (SGS) that is required for efficient prophage replication. To aid in studying the unusual properties of the SGS, we sought other gyrase sites that might be able to substitute for the SGS in Mu replication. Five candidate sites were obtained by...
