Saved By Junk DNA: Vital Role In The Evolution Of Human Genome
ScienceDaily (May 30, 2009) — Researchers at K.U. Leuven and Harvard University show that stretches of DNA previously believed to be useless ‘junk’ DNA play a vital role in the evolution of our genome. They found that unstable pieces of junk DNA help tuning gene activity and enable organisms to quickly adapt to changes in their environments. The results will be published in the journal Science.
