Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein engineering.

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 ...

Since the genetic code was first deciphered in the 1960s, our genes seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can ...

Scientists have long believed that a universal genetic code serves as a blueprint for all life on Earth, dictating the structure and function of organisms from the simplest bacteria to complex humans.

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...

Researchers have discovered a molecular 'barcode' system used by disease-causing bacteria to distinguish between beneficial and toxic molecules. Researchers at McMaster University have discovered a ...

A recent study reveals that bacteria residing within colorectal tumors form distinct ecosystems closely linked to disease ...
