Lactose operon transcription from wild-type and L8-UV5 lac promoters in Escherichia coli treated with chloramphenicol.
In cells treated with chloramphenicol and the inducer isopropyl-beta-D-thiogalacto-pyranoside, messenger ribonucleic acid transcription from the wild-type lac promoter was not detected. Transcription occurred from the mutant UV5-L8 promoter. The transcripts were of variable length; some included the whole Z gene. No major site of transcription arrest within the Z gene was apparent.
