14. Which one is incorrect?
(A)Transcription initiation by Pol I is directed by a core promoter element, which overlaps the start site, and an upstream control element (UCE). It requires two general transcription factors, SL1 and UBF.
(B)Transcription initiation by RNA polymerase I is most often directed by internal promoter elements. Two general transcription factors are required to initiate transcription of tRNA genes (TFIIIC and TFIIIB); an additional factor (TFIIIA) also is required to initiate transcription of 5S-rRNA genes.
(C)Transcription initiation by all three eukaryotic nuclear RNA polymerases requires a polymerase-specific general transcription factor that contains TBP as a subunit.
(D)Initiation by Pol I and Pol III does not require ATP hydrolysis, whereas initiation by Pol II depends on ATP hydrolysis.
