A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

An international collaborative research team has discovered that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

In May 1952, Rosalind Franklin and Raymond Gosling captured Photo 51, a crucial X-ray diffraction image revealing DNA's ...

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, according to ...

James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...

DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
