In vivo promoter activity of the synthetic Pribnow box

Abstract
The synthetic polydeoxyribonucleotides TGCA(TTATAATGCA), ??? a containing the consensus Pribnow box, were inserted upstream of the promoterless gal operon in a specially constructed plasmid. Using the MacConkey agar indicator technique it has been show that these inserts are able to induced an efficient in vivo expression of the gal operon.
