To create color, different small DNA strands linked to fluorescent molecules (markers) that can emit either red, green or blue color are hybridized to a long complementary DNA strand on the surface.

With the landmark discovery of the double-helical structure of DNA came the appreciation that the molecule’s two entwined strands are complementary — each serving as a template for the other ...

Moreover, HiDEF-seq detected changes in the DNA letter code while they were present on just one of the two strands of DNA, before they become permanent double-strand mutations.

That’s what researchers at Columbia and Brookhaven are doing—constructing intricate 3D nanostructures by harnessing the predictable folding of DNA strands.

Technology DNA nanobots can exponentially self-replicate Tiny machines made from strands of DNA can build copies of themselves, leading to exponential replication.
