A group of Japanese chemists have created a DNA molecule using almost all artificial parts--a breakthrough that may soon offer medical researchers a powerful new tool to work with. DNA holds the body's blueprint, and scientists have long marveled at its ability to store large quantities of vital information. By stitching together an artificial DNA molecule, the chemists are blazing a new path in gene therapy. The work may also apply to a new generation of computers.
"The unique chemistry of these structures and their high stability offer unprecedented possibilities for developing new biotech materials and applications," the researchers said in a statement. "The artificial DNA might be applied to a future extracellular genetic system with information storage and amplifiable abilities."
