New scientific theory based on ancient proteins suggests that genes did not arise as we believed and that life could have started elsewhere.

The findings, which detail how amino acids shaped the genetic code of ancient microorganisms, shed light on the mystery of how life began on Earth. "You see the same amino acids in every organism, ...

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...

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

Amino acids are the building blocks of life. We obtain them from the food we eat, and the body uses them to make proteins, which in turn are used for growth, development, and a multitude of other ...

Scientists at The Scripps Research Institute (TSRI) report in an upcoming article in the Journal of the American Chemical Society their synthesis of a form of the bacterium Escherichia coli with a ...
