Multiple Choice
Which of the following is NOT true regarding the differences of transcription in eukaryotes and prokaryotes?
A
Eukaryotes use multiple transcription factors to help initiate transcription.
B
Most eukaryotes have regulatory sites that are close to their promoters.
C
Most prokaryotes transcribe multiple genes under the regulation of a single operon.
D
Prokaryotic transcription factors usually interact directly with RNA polymerase while eukaryotic transcription factors do not.
Verified step by step guidance
1
Understand the process of transcription in both eukaryotes and prokaryotes. Transcription is the process by which genetic information from DNA is copied into RNA.
Identify the role of transcription factors in eukaryotes. Eukaryotic transcription requires multiple transcription factors to help initiate the process, which bind to specific DNA sequences and assist RNA polymerase in starting transcription.
Examine the structure of eukaryotic genes. In eukaryotes, regulatory sites can be located at various distances from the promoter, not necessarily close, which allows for complex regulation of gene expression.
Understand the concept of operons in prokaryotes. Prokaryotes often transcribe multiple genes under the control of a single operon, which is a cluster of genes regulated together and transcribed as a single mRNA molecule.
Clarify the interaction of transcription factors with RNA polymerase. In prokaryotes, transcription factors often interact directly with RNA polymerase to initiate transcription, whereas in eukaryotes, transcription factors typically do not interact directly with RNA polymerase but rather assist in forming a complex that facilitates transcription initiation.
