The initiation of transcription is characterized by:
A) The binding of RNA polymerase to the promoter region of the template DNA
B) The binding of DNA polymerase to the operator region of the template RNA
C) The binding of Helicase to the operator region of the template RNA
D) The binding of Ligase to the promoter region of the template DNA
E) None of these

Question

Quizplus · Accepted Answer

The initiation of transcription involves the binding of RNA polymerase to the promoter region of the template DNA, which signals the start of transcription. DNA polymerase is not involved in transcription initiation, and neither is helicase or ligase. Therefore, options B, C, and D can be eliminated. The correct answer is A.
