Generating genetic diversity lies at the heart of directed evolution which has been widely used to engineer genetic parts and gene circuits in synthetic biology. With the ever-expanding application of ...

The genetic code describes how each nucleotide triplet, or codon, of an mRNA encodes a specific amino acid or stop codon. There are 61 codons that encode 20 amino acids; most amino acids are therefore ...

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? "We find ...

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 ...

Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that keep you alive. That translation system feels so basic that it is easy to ...

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 ...
