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

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo ...

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 ...

Adenine was first discovered in 1885 by the German physiologist Albrecht Kossel. He isolated adenine from the pancreas of oxen and named it "adenine" derived from the Greek word "aden," meaning gland.

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

A piece that aired on NPR this week about the discovery of DNA's structure neglected to mention the significant contribution of Rosalind Franklin to that scientific milestone. And now some important ...
