There are some significant differences in how transcription is regulated in prokaryotes like E. coli versus eukaryotes. Which of the following statements concerning gene regulation is TRUE only in eukaryotes? (CHOOSE ALL THAT APPLY AND NO INCORRECT ANSWERS) The promoter of a gene can act in a position and distance-independent manner. The genes involved in one process are usually situated next to each other in the genome and are transcribed in one mRNA. The default state of gene transcription is...
