Chemists in Japan report development of the world's first DNA molecule
made almost entirely of artificial parts. The finding could lead to
improvements in gene therapy, futuristic nano-sized computers, and
other high-tech advances, they say.
In the new study, Masahiko Inouye and colleagues point out that
scientists have tried for years to develop artificial versions of DNA
in order to extend its amazing information storage capabilities.
As the genetic blueprint of all life forms, DNA uses the same set of
four basic building blocks, known as bases, to code for a variety of
proteins used in cell functioning and development. Until now,
scientists have only been able to craft DNA molecules with one or a few
artificial parts, including certain bases.
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
Enter the code exactly as it appears. All letters are case insensitive, there is no zero.
