Toward engineered genetics

with one comment

Researchers in Japan have created what some are calling the first DNA molecule made entirely of artificial parts.  The unnatural bases are said to be capable of forming bonds with one another similar in shape and stability to those of the molecular framework associated with naturally-occurring DNA.

For the long, technical version of the story, you can read the .html version of the article on the American Chemical Society website here.  Below is an image from the article, visually comparing the natural (top row) and unnatural (bottom row) base pairs:


The following excerpt, taken from the Conclusions section of the article, is enough to ignite my imagination with sci-fi tales of the cybernetic future of humanity:

Therefore, the present molecular framework has a potential for storing genetic information and for application to enzymatic replication directed toward engineered genetics. Furthermore, the artificial DNA may be a superior building scaffold for constructing nanostructures of materials interest because of the stable C-nucleosides against ubiquitous naturally occurring enzymes such as DNase.
