試題詳解

14. Choose a correct statement for eukaryotic promoters.
(A) Spacing between the core element and upstream promoter element (UPE) is not important for the transcription of class I promoters.
(B) At least in Drosophila, TATA-less of class II promoters tend to have downstream promoter elements (DPEs) that are similar to TATA box, bound by TFIIB.
(C) Inr (initiator) and the TATA box constitutes a core promoter for the adenovirus major late promoter.
(D) The tRNA gene contains an internal promoter, which is split into three regions: box A, a short intermediate element, and Box C.
(E) The AT-rich initiator (rINR) is a conserved sequence of class I promoters and is located within the upstream promoter element (UPE).
