Aphysiology instructor asks the students about the purpose of the promoter region on a dna strand. which student response is most accurate?

Contains amino acids that the RNA polymerase recognized and binds to, thus starting the replication process.

Explanation:

The promoter region of a DNA is where initiation of transcription of a gene takes place.

This happens when RNA polymerases and other vital  transcriptional factors bind to the promoter sequence and initiate transcription. Promoters are typically located up stream (5' end) of the transcription initiation site and the promoter sequences define direction of transcription.

The TATA box is the conserved Promoter sequence in most eukaryotes.  

the correct answer is b
