Which of the following statements about transcription in prokaryotes is incorrect?
A. In prokaryotes, a transcriptional activator
protein must bind the activator binding site
prior to RNA polymerase complex binding at
the promoter.
B. In prokaryotes, the binding of a repressor
protein to the repressor binding site prevents
the binding of RNA polymerase complex.
C. In prokaryotes, the RNA polymerase
complex will bind at the promoter in the
presence or absence of an activator protein
and transcription will proceed.
D. If an activator protein binds at site far from
the promoter sequence, transcription does
not proceed efficiently.
E. The binding sequence for an activator can
be upstream of the promoter, downstream of
the promoter, or overlapping with the
promoter sequence.
