In the initiation of the transcription of structural genes in eukaryotes, _______ cannot bind directly to the _______. Initiation requires _______ and other regulatory proteins called "_______."

Question

Quizplus · Accepted Answer

RNA polymerase II cannot bind directly to the initiation site in eukaryotes. Initiation requires TFIID and other regulatory proteins called "transcription factors." RNA polymerase I and III are involved in the transcription of ribosomal RNA and tRNA, respectively, and use different initiation factors. The TATA box is a specific sequence of DNA upstream of the initiation site that is recognized by TFIID.
