article_snippet.sent: the DNA also acts as an on-and-off switch for some genes.
article_snippet.sent: These connect together short DNA chains to form long ones, without the need for a separate biological process.
article_snippet.sent: The image shows a droplet of condensed nano-DNA and within The image smaller drops of The image liquid crystal phase which show up in polarised light on the left.
article_snippet.sent: The liquid crystal droplets act as 'micro-reactors' where short DNA can join together into long polymer chains to evolve into more complex life . '
highlights_snippet.sent: Scientists claim the process can drive the formation of chemical bonds .
