The discovery of DNA started with this overlooked scientist

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would ...

i-DNA 'peek-a-boo structures' form in living cells and regulate genes linked to cancer

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

James Watson, co-discoverer of the double-helix shape of DNA, has died at age 97

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. He was 97. The ...

Dozens of viruses seem to use a different DNA base

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in viruses, ...

Beyond the double helix: Alternative DNA conformations in ape genomes

New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great apes, ...
