to establish the mode of gene expression specified by transposon , we investigated the correlation among the homology of the dna sequence , the extent of transposon-specific transcription , the specific activity of penicillinase ( pcase ) per cell , and the transposition frequency by using two ampicillin resistance transposons ( tnas ) , tn2601 and tn2602 .
