Non-coding DNA

The vast majority of the human genome is comprised of non-coding DNA (genes only account for ~ 1.5% of the total sequence) §  Historically referred to as ‘junk DNA’, these non-coding regions are now recognised to serve other important functions §  Examples include satellite DNA, telomeres, introns, ncRNA genes and gene regulatory sequences
