In a world-first study, we have revealed and analysed remarkably preserved fragments of ancient DNA from the skin of a woolly mammoth. For the first time, we’ve been able to understand how the genetic ...

DNA is a double helix.”This is a fact so famous that it now appears in middle and high school textbooks. However, when you learn the details of how this shape was discovered, you realize it is not a ...

DNA molecules should repel one another because their backbones carry the same negative charge. Yet inside cells, DNA ...

DNA replication is happening continuously throughout the body, as many as trillions of times per day. Whenever a cell divides—whether to repair damaged tissue, replace old cells, or simply to help the ...

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to ...

Caption main figure: The rigid base-pair model is forced, using 28 constraints (indicated by red spheres), into a lefthanded superhelical path that mimics the DNA conformation in the nucleosome.

Long interspersed nuclear element-1 (LINE-1 or L1) is the only active, self-copying genetic element in the human genome—comprising about 17% of the genome. It is commonly called a "jumping gene" or ...

From a young age, Daniel Khosravinia tinkered and built numerous LEGO models, from knights to the Star Wars Death Star. This sparked his interest in how things are built, and when he learned about the ...
