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 ...

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

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 ...

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 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 ...

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 ...

This circular diagram represents the genetic code, showing how the four nucleotide bases of RNA (adenine [A], cytosine [C], guanine [G], and uracil [U]) form codons that specify amino acids. Each ...

A new CRISPR approach can control genes without cutting DNA, opening a safer path for treating genetic diseases. A newly ...

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 ...

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 ...
