Concept

Problem: Why are eukaryotic promoters more variable than bacterial promoters? Select the three correct answers.A. RNA polymerases in eukaryotes are considerably less specific, which allows promoters to be more variable.B. There are multiple transcription factors in eukaryotes, which are specific to each type of polymerase, and these bind to different promoter sequences.C. Nearby sequences in addition to the promoter consensus sequences in bacteria are thought to be important in modulating the level (rate) of transcription initiation. D. Nearby sequences in addition to the promoter consensus sequences in eukaryotes are thought to be important in modulating the level (rate) of transcription initiation.E. There are multiple RNA polymerases in eukaryotes, each of which binds to a different consensus sequence.
