What To Do With X-Large DNA?

rpiquepa writes "Before answering this question, what on earth is X-Large DNA? This news release from Stanford University says that scientists there have created a molecule of DNA wider than the ones found in living creatures in our world. They "have created an expanded molecule of DNA with a double helix wider than any found in nature. Besides being more heat resistant than natural DNA, the new version glows in the dark — a property that could prove useful in detecting genetic defects in humans." You also can read "DNA, Now in XXX-Large," from Wired News, which tells you that xDNA could be a key to find life on other planets. This summary contains more details about what is "expanded DNA," or xDNA."

    Overhyping progress

    Yes, the development is certainly great from the perspective of chemical engineering. And the development is useful from the perspective of information storage, particularly if large DNA is more stable or more resistant to free radicals than small DNA. However from the perspective of information storage we want smaller molecules not larger molecules.

    From the perspective of DNA defect diagnosis I'm not buying it at all. Its all hype until they demonstrate how it would be cheaper than existing or in-development methods. I'm speaking as an individual who has managed a significant amount of DNA genotyping and sequencing. It sounds to me (at least from the press releases) that these are chemists seeking to find an application for what is a great piece of creative chemistry who have no awareness of the realities of the biotech market.
