Question

DNA sequences that direct RNA polymerase to the initiation site are called ______________.

Answer 1

Answer: promoters

Explanation:

Promoters are DNA sequences that direct RNA polymerase to the initiation site. Promoter sequences are simply DNA sequences that helps in defining where the gene transcription by RNA polymerase will start.

Promoter sequences are located directly upstream and are an important part of the expression vectors as the binding of DNA to the RNA polymeras are being controlled by them.
