Problem

Which of the following is NOT true regarding the differences between gene transcription in eukaryotes and prokaryotes?

A. Most eukaryotes use multiple transcription factors rather than single transcription factors.

B. Most eukaryotes have regulatory sites that are close to their promoters.

C. Prokaryotic transcription factors usually interact directly with RNA polymerase while eukaryotic transciption factors do not.

D. Most prokaryotes transcribe multiple genes under the regulation of a single operon.

E. Eukaryotic transcription factors promote remodeling of the chromatin while prokaryotic transcription factors do not.

Solution

The transcription process of different organisms are regulated by different mechanisms, including the use of different transcription factors. Prokaryotes for example, are known for their use of operons, which group multiple genes with related function.
