Quizplus · Accepted Answer

The promoter of a gene is located at the 5' end of the gene and is where RNA polymerase and transcription factors bind to initiate transcription, marking the start point of transcription. Choice A and C are incorrect, as the promoter is not located at the 3' end of the gene and does not mark the end point of transcription or translation. Choice D is incorrect, as the 3' end of the gene is not involved in translation, only in transcription. Choice E is also incorrect, as the promoter is not located at the 5' end of the gene.
