Photos and letters show how James Watson and Francis Crick raced to uncover the double helix structure of DNA.

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 ...

Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

A research team has solved the three-dimensional structure of a key protein that helps damaged cellular DNA repair itself. Investigators say that knowing the chemical structure of the protein will ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

This monumental scientific achievement occurred within a context of intense international collaboration, rapid technical ...

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 ...

James Watson, who co-discovered the structure of DNA has died at age 97. He was a scientific superstar until he made racist ...

His collaboration with biophysicist Francis Crick on the molecular key to all living organisms would make him one of the most ...

Often celebrated as a pioneer of genetics alongside Francis Crick, racist and sexist remarks tarnished his reputation in ...
