First, one must know that RNA is what is used to copy the DNA, but RNA cannot work alone. There are certain “regulators” that have binding proteins that make the site, or location, for the RNA polymerase to sit down, these are called promoters. Promoters are the most important part of transcription because they are in charge of controlling genes; there are many types of promoters, depending on their location on the strand of DNA. For example, the core or basal promoter is the minimal portion of the promoter required to properly initiate transcription, it contains the Transcription Start Site (AUG), the binding site for RNA polymerase, and general transcription factors. Promoters contain the cis- acting regulatory region that enables the writing or transcription of other codons. There are also proximal and distal
