A gene being transcribed uses transcription factors to recruit RNA polymerase II to the DNA at the promoter region. After the polymerase is recruited, transcription elongation occurs, and nucleotides are added to the transcript in the 5'-3' direction. How do you know that the gene being transcribed is not a prokaryotic gene?
A) In prokaryotes, the promoter comes after the transcription unit.
B) Prokaryotes do not have promoters.
C) In prokaryotes, nucleotides are added to the transcript in the 3'-5' direction.
D) Prokaryotes use ribosomes rather than RNA polymerase to transcribe genes.
E) In prokaryotes, RNA polymerase binds directly to DNA at the promoter without transcription factors.

Quizplus · Accepted Answer

In prokaryotes, RNA polymerase can directly bind to the DNA at the promoter region without the need for transcription factors, which are required in eukaryotic transcription.
