B)binding of a transcription factor to the transcription bubble, followed by recruitment of additional transcription factors and recruitment of RNA polymerase III
C)binding of the sigma subunit to the start site followed by recruitment of RNA polymerase II
D)binding of RNA polymerase II to the TATA box, followed by recruitment of transcription factors

Question

Quizplus · Accepted Answer

In eukaryotes, the transcription initiation complex is formed when a transcription factor binds to the TATA box, which is a DNA sequence found in the promoter region. This initial binding is followed by the recruitment of additional transcription factors and RNA polymerase II, which is responsible for transcribing mRNA.
