transcription initiation


Ve showed earlier [101 that the region of the bla promoter of Tn3 protected by the RHA-polymerase (REAP), has the normal size (about 60bp) at RJAP/promoter molar ratio r(2, but rises to about twice this extent as r increases. Ve confirm here that the species corresponding to normal and extended footprint distinguish by their electrophoretic mobilities… (More)
