DNA origami, a fascinating technology that uses algorithms to design self-assembling 2- and 3D nanostructures using DNA helices, has added a new member to its growing catalog: multilayered ...

For 60 years, the DNA double helix has provided an iconic image of how our genetic information is held and how it reproduces. Now scientists at the University of Cambridge in the UK – where Watson and ...

BERKELEY, CA – Repairing breaks in the two strands of the DNA double helix is critical for avoiding cancer. In humans and other organisms, a molecular machine called the MRN complex is responsible for ...

Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form ...

When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...

The tiny motor could help spark research into future applications such as building molecular factories for useful chemicals or medical probes of molecules inside the bloodstream to detect diseases ...

DNA, the medium of life, is so deeply associated with the biochemical world that considering its nonbiological applications may seem far-fetched. However, for researchers in the 1980s and 1990s ...

Researchers from Tokyo Metropolitan University have identified key factors in the mechanism behind DNA repair in our bodies. For the first time, they showed that the "proofreading" portion of the DNA ...

Experiments with DNA molecules show that their mechanical properties are completely different from what those of macroscopic objects - and this has important consequences for biology and medicine.
