Stretches of DNA previously believed to be useless 'junk' DNA play a vital role in the evolution of our genome, researchers have now shown. They found that unstable pieces of junk DNA help tuning gene activity and enable organisms to quickly adapt to changes in their environments.
A large portion of the human genome (approximately 98 percent) does not encode genes. Long thought to be "junk DNA," these portions, researchers continue to learn, can play a role in genetic activity and, subsequently, in health and... Read Post
A new UC San Francisco study highlights the potential importance of the vast majority of human DNA that lies outside of genes within the cell. The researchers found that about 85 percent of these stretches of DNA make RNA, a molecul... Read Post
