Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing ...
Industrial yeasts are a powerhouse of protein production, used to manufacture vaccines, biopharmaceuticals, and other useful ...
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 ...
RNA therapeutics target translation rather than DNA, aiming to correct shared protein production errors. By enabling cells to read through premature stop codons, engineered tRNAs could restore ...
Most organisms on Earth have the same basic genetic code, but it comes with some flaws. Scientists sought to work out those errors by creating their own artificial genome, which replaced E. coli’s ...
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 ...
Liquid culture flasks of bacteria grown in yellow broth covered with tinfoil on a shaker. Bacterial strains needed to be tested every step of the way to create the highly compressed genome. Credit: ...
Tinkers are complexes of amino acid polymers (colored spheres) and DNA flipons (wireframes). Tinkers self-amplify with DNA and peptide strands promoting the synthesis of each other. Early on, tinkers ...
