Which of the following relates to the transcription of a eukaryotic mRNA gene?
A) begins only when repressors are removed from nucleosomes in which the gene lies

D) requires binding of TFIID to the TATA box
E) requires eIF-2

Question

Transcription of a eukaryotic mRNA gene requires the binding of TFIID to the TATA box, which is a crucial step in the formation of the transcription initiation complex.  There are numerous protein factors controlling transcription initiation. Two basal promoter elements that are found in essentially all eukaryotic mRNA genes are the TATA box and the CAAT box. Many of the basal transcription factors are identified by the fact that they control the activity of RNA pol II. Thus, the nomenclature of these proteins is TFII, for transcription factor of RNA pol II. TFIID is the factor that binds to the TATA-box.
