Human DNA constantly refolds in 3D space, and these looping dynamics regulate gene expression and cell identity.
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, ...
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 ...
New work shows that physical folding of the genome to control genes located far away may have been a critical turning point for life on Earth. For evolutionary biologists, what most distinguishes the ...
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 ...
A program aimed at helping Black residents trace their ancestry, and in some cases, reconnect with living relatives in Africa, is expanding across the state of Illinois. The Illinois Family Roots ...
Add Yahoo as a preferred source to see more of our stories on Google. In May 2025, online users shared and discussed a rumor about Britain's Princess Beatrice, the elder daughter of Prince Andrew and ...

Spit in a tube and, for about $100, discover secrets held by your DNA. That was the promise of 23andMe, a direct-to-consumer genetic-testing company. It proved popular—more than 15m customers coughed ...
Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...
DNA is often compared to a written language. The metaphor leaps out: Like letters of the alphabet, molecules (the nucleotide bases A, T, C and G, for adenine, thymine, cytosine and guanine) are ...
