Whats does regulatory DNA do? Is regulatory DNA transcribed then translated into protein?

A gene must have regulatory sequences associated with it. These are stretches of DNA which do not themselves code for protein but which act as binding sites for RNA polymerase and its accessory molecules as well as a variety of transcription factors. Together, the regulatory sequences with their bound proteins act as molecular switches that determine the activity state of the gene - e.g. OFF or FULL-ON or, more often, something in between. The regulatory sequences include the promoter region together with enhancer elements.
