Living organisms synthesize a staggering variety of proteins by combining 20 amino acids into chains of any length and order. In the past, to expand protein diversity beyond the scope of these 20 ...
Starting from the four innermost letters and working to the outermost ring, this table shows shows which three-letter base sequence or codon encodes which amino acid. In the journal Angewandte Chemie ...
Scientists trying to engineer biologic molecules with new functions have long felt limited by the 20 amino-acid building blocks. Researchers are working to develop ways of putting new building ...
It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...

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 ...
The code of life is simple. Four genetic letters arranged in triplets—called codons—encode amino acids. These are the building blocks of proteins, the machinery that powers life. But the genetic code ...
A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...
Mutations can occur on several levels, including genetic, but can also take the form of amino acid replacements during protein synthesis. Amino acid replacements can be deleterious, neutral, or ...
