Which of the following is characteristic of genes and gene regulation in eukaryotes, but not bacteria? (a) enhancers (b) transcription factors (c) promoters (d) a and b only (e) a, b, and c are found in eukaryotes but not bacteria
Which one of the following is the main reason that a typical eukaryotic gene is able to respond to a far greater variety of regulatory signals than a typical prokaryotic gene or operon? A. Eukaryotes have three types of RNA polymerase. B. Eukaryotic RNA polymerases require general transcription factors. C. The transcription of a eukaryotic gene can be influenced by proteins that bind far from the promoter. D. Prokaryotic genes are packaged into nucleosomes.
