7. What is the main reason that a typical eukaryotic gene is able to respond to a far greater variety of regulatory signals than a typical bacterial (prokaryotic) gene or operon? A) Eukaryotic gene transcription can be influenced by proteins that bind far from the promoter. B) Eukaryotes have transcriptional activators and repressors. C) Eukaryotes have three types of RNA polymerase. D) The protein-coding regions of eukaryotic genes are longer than those of bacterial genes.
