Ars Technica A series of triplets, stretched out along the DNA, can be read to determine the precise order of amino acids . At the end of the list of amino acid codes, you'll find what's called a stop codon. The three stop codons (TAA, TAG, and TGA in their DNA form ...
Scope (blog) The machines responsible for that assembly are called ribosomes – as many as 10 million of them within a single mammalian cell, each capable of stapling together up to 200 amino acids (the building blocks of proteins) per second. The resulting amino ... and more »
Food Safety News New research suggests that an amino acid is what affects the behavior of E. coli O157. A University of Glasgow team analyzed the genome sequence of 1,500 strains of E. coli to see how the genes of the pathogen respond to different concentrations of ...
BioTechniques.com Here we present a procedure for preparing amino acid mixtures—having both the desired composition and a physiological pH—at high concentrations for cell-free expression systems. Up to 2.1 mg/mL of active protein was synthesized in batch mode ...
GenomeWeb NEW YORK (GenomeWeb) – Researchers at the University of Washington have developed a method to enable researchers to perform site-directed, single amino acid mutagenesis. By relying on microarray-based DNA synthesis and overlap-extension ...
NPR (blog) But George Church, a professor of genetics at Harvard Medical School, has created a bacterium that requires an additional amino acid , one made in the lab an...
R & D Magazine The Yale researchers rewrote the DNA of a strain of bacteria so that it requires the presence of a special synthetic amino acid that does not exist in n...
