A promoter in a transcription unit is a DNA sequence ________.
A promoter in a transcription unit is a DNA sequence ________.
Options
- Awhich appears in processed RNA
- Bthat provides a binding site for RNA polymerase
- Cwhich terminates the transcription process
- Dthat provides the binding site for DNA polymerase
Correct answer
B. that provides a binding site for RNA polymerase
Step-by-step solution
A promoter is a specific DNA sequence in a transcription unit that provides a binding site for RNA polymerase and transcription factors to initiate the process of transcription.
It is located towards the end (upstream) of the structural gene with respect to the coding strand.
The promoter itself is not transcribed into RNA, nor does it terminate transcription (which is the function of the terminator sequence). DNA polymerase binds to origins of replication during DNA replication, not to promoters during transcription.
