Which Molecules are Not Part of the Closed Promoter Complex

Question

Which molecules are not part of the closed promoter complex?
A) RNA polymerase
B) Transcription factors
C) Double helix DNA
D) Single-stranded DNA

Accepted Answer

The closed promoter complex is formed when transcription factors bind to the promoter region of double helix DNA and recruit RNA polymerase to initiate transcription. Single-stranded DNA is not involved in the formation of the closed promoter complex.
