A convenient motif-searching program has been developed, based on a double correlation algorithm, for analysis of the pulse character of Escherichia coli transcription. Activity in the zone of minimal pause formation ( 1,2 bp) is precisely determined. Oligonucleotides (di-, tri- and tetranucleotides) are randomized by their pause-generating activity. CATG and CATGC are detected which coincide with the primary structure of RNA associated with distinictive delays in biologically meaningful situations.
