The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

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 during ...

DNA has been used for years to store data, but encoding information into the molecule is painstaking work. Now, researchers have drastically sped it up by mimicking a natural biological process that ...

Nanoscale “robots” made of DNA that rapidly self-replicate could be harnessed to manufacture drugs or other chemicals inside the body, say researchers. Tiny machines made of DNA origami may make ...
