But DNA doesn't always assume this form. The existence of one shape of DNA in humans, in particular — a four-stranded knot of genetic code — has been controversial among scientists for years.

The team created as many as 4,096 specific symbols that can be inserted, and demonstrated that the DNA Typewriter can lay them out in order to form full sentences that can be read back later.

Full details of the work are published in a new Science Advances paper titled, “ Counter ions influence the isothermal self-assembly of DNA nanostructures.” ...

FULL STORY. In the form of DNA, nature shows how data can be stored in a space-saving and long-term manner. Bioinformatics specialists are developing DNA chips for computer technology.

FULL STORY. Just like any long polymer chain, DNA tends to form knots. Using technology that allows them to stretch DNA molecules and image the behavior of these knots, ...
