(Phys.org)—When a cell divides, it passes on genetic information by producing copies of its DNA. Chemists have also learned to copy DNA.

Unlike earlier methods, it allows for stepwise growth of the chain in both the direction preferred by nature and the opposite direction typical of current DNA synthesis techniques.
