Researchers in the US and Germany have developed a new way to transform DNA into complex shapes by making the molecules twist and bend. The technique could be crucial for making nanoscale device ...

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 ...

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 ...

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 ...

DNA origami is a technique used for the nanoscale folding of DNA to develop two-dimensional (2D) and three-dimensional (3D) shapes at a nanoscale range. No bigger than a virus, each of these ...

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 ...

(Nanowerk News) A human cell harbors roughly 2 meters of DNA, encompassing the essential genetic information of an individual. If one were to unwind and stretch out all the DNA contained within a ...

Homologous recombination is one mechanism for repairing double-stranded DNA breaks. It involves the exchange of nucleotide sequences to repair damaged bases on both strands of DNA through the ...
