61 codons specify one of the 20 amino acids that make up proteins 3 codons are stop codons, which signal the termination of protein synthesis Importantly, the genetic code is nearly universal, shared ...

Two-faced codon rewrites genetics? The genetics of a marine protozoan may overturn one of the long-held tenets of protein synthesis. According to conventional wisdom, the genetic code is unambiguous: ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that’s added to a chain of amino acids ...

This article reconsiders the theoretical role of the genetic code. By drawing on published and unpublished sources from the 1950s, I analyse how the code metaphor was actually employed by the ...

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 ...

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 ...

As wildly diverse as life on Earth is — whether it’s a jaguar hunting down a deer in the Amazon, an orchid vine spiraling around a tree in Congo, primitive cells growing in boiling hot springs in ...

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 ...
