“Junk” DNA iGraphic
By Duncan Mil
September 20, 2012 - A global team of scientists has discovered that so-called “junk” DNA in the human genome is a vast switchboard, linking millions of regulators that turn genes on or off to make proteins, the basic molecules of life. Scientists working on the Encode Project analysed more than 150 types of human cells, found that 80% of our genome performs specific functions, and identified four million gene switches.
