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 ...

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 ...

Pyrrolysine is an important component of methyltransferase enzymes, which the archaea use to metabolize methylamine in the environment. “The need for that metabolism and availability of the machinery ...

In the largest screen to date for alternative genetic codes, a computer program named Codetta scanned more than 250,000 genome sequences from bacteria and archaea to identify five never-before-seen ...

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 ...

Families of children with rare genetic conditions can get a diagnosis years faster thanks to advances in whole genome ...

Scientists trace Leonardo da Vinci's DNA through his descendants and family tombs to reconstruct his genetic code.

Orangutans, mice, and horses are covered with it, but humans aren't. Why we have significantly less body hair than most other mammals has long remained a mystery. But a first-of-its-kind comparison of ...
