Quizplus · Accepted Answer

Transcription can only occur when the DNA is in an open promoter complex. In this complex, the DNA strands are separated and available for RNA polymerase to bind and begin transcribing the DNA sequence. The closed promoter complex occurs before transcription initiation and the biphasic promoter complex is not a recognized complex in transcription.
