Nirenberg's Genetic Code Chart, 1961-66 On May 27, 1961, Heinrich Matthaei, a postdoc working with NIH scientist Marshal Nirenberg, placed synthetic polyuracil RNA into 20 test tubes to see what it ...

In a giant feat of genetic engineering, scientists have created bacteria that make proteins in a radically different way than all natural species do.

Darwin's theory of evolution should be expanded to include consideration of a DNA stability 'energy code' -- so-called 'molecular Darwinism' -- to further account for the long-term survival of ...

Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us.

The fish's DNA code expanded dramatically over the past 100 million years of evolutionary history, racking up the equivalent of one human genome every 10 million years, researchers found.
