The region of DNA where RNA synthesis begins is the ______.

Question

Quizplus · Accepted Answer

The promoter is the region of DNA where RNA synthesis begins. It is the site where RNA polymerase binds and initiates transcription. The start codon is a sequence of nucleotides in mRNA that signals the ribosome to begin translation, and is not directly involved in RNA synthesis. The terms initiator and processor are not typically used to describe the region where RNA synthesis begins.
