DNA that does not code for a protein. Not all DNA codes for proteins. Some DNA between genes is needed to help the genetic machinery express the genes. DNA also contains segments that are repeated many times.
One of the two identical strands that make up the DNA double helix. The non-coding strand, or antisense strand, is a mirror-image of the coding strand, but does not carry the information needed to order the production of proteins.
The strand of DNA that does not carry the information necessary to make a protein. The non-coding strand is the mirror image of the coding strand and is also known as the antisense strand.
Also referred to as " Junk DNA", non-coding DNA has no known biological function.
Regions of the DNA molecule that do not code for proteins - popularly, but incorrectly, referred to as 'junk DNA'.
Also referred to as ' junk DNA,' non-coding DNA is not part of an active gene that contains a code for making a protein. Recent evidence shows that at least some non-coding DNA is involved in biological processes such as regulation of gene expression and chemical signaling among cells. All testing for genealogical purposes is done on non-coding DNA, which makes up nearly 98% of human DNA
