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 ...

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 ...

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 ...

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 ...

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 ...

你的DNA并非全部来自人，还有一些来自古老的病毒DNA。多年来，科学家们一直认为这些病毒遗留物只是在积灰，是无害的进化历史遗物。然而事实真的是这样的吗？ 由科罗拉多大学生物前沿研究所助理教授Edward Chuong博士领导，并发表在《科学进展》杂志上的 ...
