In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix—Crick laid out what he called the “central dogma” of molecular ...

Diagrams: Short section of DNA, 1951 -- Chemical structures of the DNA bases, 1951 -- Covalent bonds of the sugar-phosphate backbone -- Schematic view of a nucleotide -- Mg** ions binding phosphate ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a double helix. That picture is still right, but it is no longer enough.

The scientist who discovered hybridization and the "other" double helix describes what it meant to biology. By Alexander Rich Fifty-two years ago I was venturing to the basement of Cal Tech chemistry ...

(AP) - 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. He was ...

I have never seen Francis Crick in a modest mood.” James Watson’s mischievous opening line of The Double Helix raised many eyebrows at the time, but even Crick wouldn’t quarrel with it now. Still ...

DNA is the poster child for high-specificity binding. As long as their base sequences match, two complementary strands of DNA can navigate through a sea of biomolecules, find each other, and hold fast ...

The origin of life is surely one of the most important questions in biology. How did inanimate molecules give rise to the ...

Scientists have designed a new method for detecting and analyzing double-stranded RNA during the manufacture of messenger RNA products. The team of Anubhav Tripathi, PhD, from Brown University, claim ...
