codons

Self-contained synthetic E. coli resistant to viral infection could prove invaluable to the biotechnology industry by increasing product consistency and reducing safety concerns. 

A massive screen of bacterial and archaeal genomes revealed five previously unknown instances where an organism uses an alternate code to translate genetic blueprints into proteins.

Study shows the viability of bacteria with human-made, recoded DNA.

Some ciliates use the same trio of nucleotides to code for an amino acid and to stop translation.

Traditional stop codons have a double meaning in the protozoans' mRNA, sometimes calling for an amino acid during translation.

Scientists design a bacterial genome with only 57 codons.

A free algorithm helps synthetic biologists decide which codons to use to encode repetitive proteins using the least-repetitive DNA sequence possible.

A survey of trillions of base pairs of microbial DNA reveals a considerable degree of stop codon reassignment.

Rewriting the genetic code can lead to a better understanding of how living cells work, and spawn new biotechnological applications.

Leonard Lerman, who helped elucidate the process from gene to protein, passed away last month at age 87.

Roger Kornberg, one of Arthur's boys, has a Sydney Brenner story. We all do, but his is more telling than most.
