In the process of transcription, what is a promoter?
A
A sequence of RNA that signals the end of transcription
B
A protein that unwinds the DNA double helix
C
A molecule that transports amino acids to the ribosome
D
A sequence of DNA where RNA polymerase binds to initiate transcription
Verified step by step guidance1
Understand that transcription is the process of synthesizing RNA from a DNA template.
Recognize that a promoter is a specific sequence of DNA, not RNA, that plays a crucial role in transcription.
Identify the function of a promoter: it is the site where RNA polymerase binds to the DNA to start the transcription process.
Differentiate between the roles of various molecules in transcription: RNA polymerase is the enzyme that synthesizes RNA, while the promoter is the DNA sequence that signals where this process should begin.
Clarify that the promoter is not involved in ending transcription, unwinding DNA, or transporting amino acids, but specifically in initiating transcription by providing a binding site for RNA polymerase.
