This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

DNA sequences with the potential to form unusual conformations, which are frequently associated with cancer and neurological diseases, can in fact slow down or speed up the DNA synthesis process and ...

Scientists have constructed ''DNA droplets'' comprising designed DNA nanostructures. The droplets exhibit dynamic functions such as fusion, fission, Janus-shape formation, and protein capture. Their ...

As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...

James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...

Over the past decades, a growing number of robotics teams have started developing modular robots inspired by the ancient ...

Every face carries a story, shaped long before birth by a quiet choreography of genes switching on and off at just the right moment. A new study suggests that part of that story reaches far back into ...
