Transcription in Eukaryotes Requires Which of the Following in Addition

Question

Transcription in eukaryotes requires which of the following in addition to RNA polymerase?
A)the protein product of the promoter
B)start and stop codons
C)ribosomes and tRNA
D)several transcription factors (TFs)
E)aminoacyl synthetase

Accepted Answer

Eukaryotic transcription requires several transcription factors (TFs) to bind to the promoter region and appropriately position RNA polymerase for transcription to occur. The protein product of the promoter (choice A) is not necessary for transcription, as the promoter itself acts as a DNA sequence that signals the start site of transcription. Start and stop codons (choice B) are important for translation, but not transcription. Ribosomes and tRNA (choice C) are also necessary for translation, not transcription. Aminoacyl synthetase (choice E) is not directly involved in either transcription or translation.
