Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

In the new work, Rothemund and his colleagues used DNA origami to create a lilypad-like structure—a flat, circular surface about 100 nanometers in diameter, tethered by a DNA linker to a gold ...

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...
