Promoters and transcription factors

WebInducers can also bind to activator proteins, allowing them to bind to the operator DNA where they promote RNA transcription. Eukaryotic cells have much more complicated regulation of gene expression. Inducers and their mechanisms in … WebRNA Polymerase II Promoters and Transcription Factors. Eukaryotic promoters are much larger and more intricate than prokaryotic promoters. However, both have a sequence similar to the -10 sequence of prokaryotes. In eukaryotes, this sequence is called the TATA box, and has the consensus sequence TATAAA on the coding strand.
