What is the part of a strand of DNA with regulatory sequences?

Noncoding gene sequences control gene expression. You may also be thinking of what is called "junk DNA" which is not junk. We just do not know what all of it codes for.


Why is the outdated term junk DNA a misnomer for noncoding regions of the human genome?

The conservation of "junk DNA" sequences in diverse genomes suggests that they have important functions.
