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 ...

Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or codons—specify one of many amino acids, the building blocks of proteins. Multiple ...

Synthetic biologists from Yale were able to re-write the genetic code of an organism—a novel genomically recoded organism (GRO) with one stop codon—using a cellular platform that they developed ...

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 ...

The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...

Proteins are built by mixing and matching amino acids, but researchers want to create new functions by adding noncanonical amino acids (ncAAs). However, this process often requires complex whole ...

DNA is admired for its perfection as a programmable information molecule: it uses repeating polymerization chemistry to link four nucleotide building blocks (adenine, cytosine, guanine, and thymine) ...
