First DNA molecule made from (almost) entirely Artificial Parts

Bit late to the party on this one, but it’s definitely worth noting.

Chemists at a University in Japan are reporting the first artificially synthesised DNA molecule.

The researchers used high-tech DNA synthesis equipment to stitch together four entirely new, artificial bases inside the sugar-based framework of a DNA molecule. This resulted in unusually stable, double-stranded structures resembling natural DNA.

Like natural DNA, the new structures were right-handed and some easily formed triple-stranded structures. The unique chemistry of these structures and their high stability offer unprecedented possibilities for developing new biotech materials and applications, the researchers say.
