Recombination between tryptophan gene mutations within the trp operon was determined among transductants for an outside linked cysB marker under conditions of repression and derepression. These studies, carried out with recipient strains utilizing the RecBC or RecF pathway, or a combination of these pathways of recombination, demonstrate that transcription of trp genes as regulated by the trp repressor has no significant effect on RecBC- or RecF-mediated recombination within the trp operon.
