The genetic code is not frozen. Genetic code variations found in microorganisms include codon bias, codon reassignment, ambiguous decoding and natural genetic code expansion. Codon bias, which is ...

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 would produce. Each tube contained ...

Genetic networks have been identified in human cells, say researchers, noting that the study has also found potential targets for cancer therapy. Cancer is a heterogeneous disease, with myriad ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

While testing a new way to sequence genes, researchers stumbled upon a very rare divergence in the genetic code, which translates genetic sequences into proteins. The discovery was made in an organism ...
