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 ...

We have determined the crystal structure of a four-way DNA junction by multiwavelength anomalous diffraction, and refined it to 2.16 Å resolution. The structure has two-fold symmetry, with ...

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 ...

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, the ...

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 ...

Although the genetic sequence is the same in every cell in the body, only a subset of those genes is expressed by each cell.

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

A generative AI-based technique can predict thousands of 3D genomic structures in just minutes, enabling researchers to more ...

The way the body ages could be more resilient than previously thought, a new study suggests.

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 ...

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...
