the derepressed rna , when hybridized with the separated strands of hphi80dargec-i imm ( lambda ) phage dna ( the arginine genes are inversely inserted in this phage ) , which has a deletion in gene e and extends to gene c of the argecbh cluster , showed no leftward transcription , whereas the rightward transcription was reduced to about 40 % of that when the dna carrying the entire ecbh cluster was used for hybridization .
