The traditional explanation of the initial genetic code in life seems less established when ancient proteins seem to be ...

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...

It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

New research from the Champalimaud Foundation (CF) reveals how missing just one essential amino acid can change gene expression and the brain's sensory systems, prompting animals to seek out ...

Consuming over 22% of dietary calories from protein can lead to increased activation of immune cells that play a role in atherosclerotic plaque formation and drive the disease risk, new study showed.
