What is regulatory DNA?

Regulatory DNA consists of promoters, enhancers, silencers, and insulators.
The regions of DNA that contain these used to be called "junk" DNA as no one yet knew what they coded for.
Scientists are beginning to exam these areas called junk DNA (97%) of all of our DNA.
The vast majority of the transcribed RNA is involved in the control of the expression of the genes themselves. In addition, the DNA from which regulatory RNA is transcribed may be very distant from the genes they control, even situated on different chromosomes.
Very little seems to be known yet about these segments of DNA.
