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 ...

The synthetic bacteria contain a shorter genetic code with 57 codons rather than 64, freeing up space for further edits that might lead to new drugs or virus-resistant microbes ...

The recoded bacterium uses only 57 of the 64 possible genetic codes, freeing up seven to be used for different purposes ...

DNA contains foundational information needed to sustain life. Understanding how this information is stored and organized has been one of the greatest scientific challenges of the last century.

Two-faced codon rewrites genetics? The genetics of a marine protozoan may overturn one of the long-held tenets of protein synthesis. According to conventional wisdom, the genetic code is unambiguous: ...

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.

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 ...

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

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.
