The world’s most famous molecule – the DNA double helix – sometimes doubles up again. Researchers have now found this quadruple-stranded form in healthy human cells for the first time. Four-stranded ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

The results of this collaborative project overturn some conventional wisdom about how the DNA repair process works. DNA is often likened to a blueprint. The particular sequence of As, Cs, Gs, and Ts ...

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and the woman who was left out of the accolades. By Bill Gourgey Published May 31, 2022 7:00 AM EDT Get the Popular Science ...

Cockayne syndrome (CS) is a rare disease that causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. A new study by researchers from the ...

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, ...

DNA is often likened to a blueprint. The particular sequence of As, Cs, Gs, and Ts in DNA provides information for building an organism. What’s not captured by this analogy is the fact that our DNA ...
