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

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 ...

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 ...

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged. Cellular DNA is continuously exposed to both ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

Most cancer cells have genomes that are much less methylated than those of normal cells, but whether this loss of methylation, an epigenetic process, has any functional meaning for the cells has long ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

Estrogen is known as an important hormone, and it can control many cellular and bodily functions by regulating the activity of hundreds of genes. Scientists have now learned more about how estrogen ...

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