Abstract
Transcriptional complexes formed in vitro with coliphage T5 DNA as template were analyzed by electron microscopy and the number and location of starting sites utilized by E. coli RNA polymerase were determined. Of the 40 promoters characterized in this way, 6 map in the two terminal "pre-early" regions, 29 in the "early" and 5 in the "late" region. The direction of transcription within the different regions determined in this study agrees with earlier findings derived from RNA synthesized in vivo.Entities:
