Which of the following statements concerning the sequence of events involved in the initiation of transcription by E. coli RNA polymerase are correct? ( can bemore than one) A.)Initiation starts with a pyrimidine nucleotide triphosphate. B.)The sigma factor (σ) functions during initiation of transcription. C.)Initiation starts with a purine nucleotide triphosphate, which is destined to become the 5'-end of RNA. D.)Initiation starts with a purine nucleotide triphosphate, which is destined to become the 3'-end of RNA. E.)RNA polymerase binds to the DNA at a point approximately 35 bp upstream of the start of transcription, at a sequence TTGACA. F.)The sigma factor does not dissociate until RNA elongation is complete.
