Whole genome sequencing is a technique that allows medics to looks at a person’s entire genetic code from a blood test.

Scientists have created Syn57, a completely synthetic bacterium with a genetic code unlike anything in nature. Unlike all known life, which uses 64 codons to build proteins, Syn57 only uses 57 — ...

In a giant feat of genetic engineering, scientists have created bacteria that make proteins in a radically different way than all natural species do. By Carl Zimmer At the heart of all life is a code.

The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...
