UC Berkeley scientists discovered that a microbe can interpret the UAG stop codon in two ways, producing different proteins ...

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 ...

The DNA inside of living organisms is packed with information, so much so that it's hard to search genetic databases, but ...

All living things on Earth use a version of the same genetic code. Every cell makes proteins using the same 20 amino acids. Ribosomes, the protein-making machinery within cells, read the genetic code ...

In a special edition of GEN Live to wrap up 2025, we are thrilled to welcome special guest Matthew Cobb, PhD, author of a wonderful new biography of Francis Crick, PhD, entitled CRICK: A Mind in ...

The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code. Andrzej Wojcicki/Science Photo Library via Getty Images Nearly all life, from bacteria ...
