Human DNA constantly refolds in 3D space, and these looping dynamics regulate gene expression and cell identity.

Authorities confirm the DNA belongs to Nancy Guthrie, 84, who was last seen on Jan. 31 at her home in Arizona A sheriff in Arizona tells PEOPLE that investigators discovered "biological DNA" evidence ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

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 Dewey Watson, a molecular biologist whose work helped decode the structure of DNA, died on November 6, 2025, at a hospice in East Northport, N.Y. He was 97 years old. Watson was best known for ...

His decoding of the blueprint for life with Francis H.C. Crick made him one of the most important scientists of the 20th century. He wrote a celebrated memoir and later ignited an uproar with racist ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. The cassette tape. A staple of the Walkmans, car stereos, and ...

Lily Wood is forty-three years old but considers April 9, 2019, to be her “rebirth day.” That was the date she received her results from Ancestry, the direct-to-consumer DNA-testing company. A ...

Cancer’s genetic fingerprints may lurk in people’s blood long before they find out about the disease. It’s possible to spot tumor DNA more than three years before a person is diagnosed with cancer, ...
