Identify the statements that are features of a promoter. Pick all that Apply.
A. In eukaryotes, the promoter recruits the preinitiation complex, which includes the TATA-binding protein.
b. In prokaryotes, the promoter is recognized by general transcription factors (GTF), which recruit the RNA polymerase holoenzyme.
c. In eukaryotes, the promoter attracts the small and large ribosomal subunits with the help of initiation factors.
d. In prokaryotes, the promoter contains a –35 and –10 region upstream of the transcription start site
e. In both prokaryotes and eukaryotes, the promoter is located in the 5\' direction, upstream from the transcription start site.
