The genetic code, a universal blueprint for life, governs how DNA and RNA sequences translate into proteins. While its complexity has inspired generations of scientists, its origins remain a topic of ...

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 ...

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

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 ...

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 ...

A new wave of gene therapy treatments offer a new lease on life for people with inherited diseases such as haemophilia. But ...

The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins. The genetic code is a set ...

Researchers have reconstructed a long string of genetic code for what they believe is the common ancestor of placental mammals — a shrewlike creature that lived in Asia more than 75 million years ago.

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...
