1. How does organisms control where transcription begins it starts? 2. In eukaryotic cells, assembly of basal transcription factors via TBP usually begins at sequence in the promoter. 3. Which TF is responsible for binding first to the promoter? 4. Which subunit within the TFIID protein complex binds to the TATA box? 5. One major difference between bacterial and eukaryotic RNA polymerase is that: a. prokaryotes have several RNA polymerases. b. eukaryotic RNA polymerase can polymerize RNA in the 3 to 5 direction. c. prokaryotic RNA polymerase recognizes several different promoters. d. eukaryotic RNA polymerase has only one polypeptide. e. eukaryotic RNA polymerase cannot read DNA to find the promoter sequence..
