Scientists uncover clues to the mystery of 'gene deserts'
...I and LBNL scientists were recently able to remove giant
chunks of gene desert DNA - whole chapters in the "book of life" - from laboratory mice with no apparent effect on the animals. Many of the deleted sequences are shared by mice and humans, and thus may have no function in humans as well. In an ef...
