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 ...

Just like the government uses an Aadhaar number to uniquely identify an individual for social security purposes, a person’s DNA fingerprint can be used for biological purposes. This is why DNA ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

This structure, announced in their famous paper in the April 1953 issue of Nature, explained how the DNA molecule could replicate itself during cell division, enabling organisms to reproduce ...

“This work was transformative: it explained findings from the last ... that researchers can also manipulate and measure the DNA’s structure. When the DNA strands were stretched by the tweezers ...

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 ...

This image compares three DNA sequencing technologies: Sanger sequencing, Massively Parallel DNA sequencing, and Nanopore DNA sequencing. Sanger sequencing (left) sequences 500-700 bases per reaction ...

"Our history is far richer and more complex than we imagined," said human evolutionary geneticist Aylwyn Scally.
