Rewriting Biology’s Rules: Scientists Have Expanded the Genetic Alphabet To Create New Proteins

Scripps Research scientists have created a method using four-nucleotide codons to incorporate non-canonical amino acids into proteins, expanding protein engineering possibilities without requiring genome-wide edits. This method has been tested in creating new peptides and holds potential for applications in various fields. In every introductory biology class, it’s a fundamental concept: proteins are made from [...]
