DNA twisted into boxes Answered

A news article in Nature reports on a group that has constructed three dimensional boxes, including a lockable lid, from DNA. Using specifically designed oligonuclitides, the boxes self-assemble chemically from long strands of DNA in solution. According to the article, "It takes only an hour or two for billions of boxes to form by themselves."

The article include both "artists conceptions" and electron-microscope images of the actual objects.

Update 13 May 2009: The Nature article above has been put into restricted access. Here is a Science News report which is not restricted.

I meant "left" (the fuzzy, blobbly one), rather than the nice neat "basket-weaving" artist's impressions. My thanks to W'burg for correcting my chirality error.

Sorry about that. I see the same restriction myself. I've added a link to the Science News writeup which doesn't have any liimits.

I added the link to the main body of the topic, in the final sentence which begins "Update".

Were you able to follow the link to the article? If not, please let me know (some of the stuff from Nature is free, some is subscription-only)/ If you were able to read the article, perhaps you could be more specific about what you didn't understand. The authors addressed your questions rather directly, I thought.

. I'm guessing posting the URL here bumped it up on the search engines and it started getting popular enough that they thought ppl would register to see it. But I'm just a good ol' boy from S AR (US).

Wow! That's fascinating - I hadn't realized you could manipulate the shape of DNA that way.
