Term Definition
Junk DNA DNA which does not code for proteins. So-called 'junk' DNA makes up over 95% of our total DNA content. Although lack of understanding of the function of this DNA led to its name, junk DNA is now known to be critical for the regulation of genes, for providing templates for evolutionary processes, for regulating chromosome replication, and many other processes. The vast majority of genetic variation occurs in regions of DNA that does not code for proteins, which include intervening sequences (introns), regulatory regions (such as promoters and enhancers), and many other sorts of non-protein coding DNA.
