The traditional explanation of the initial genetic code in life seems less established when ancient proteins seem to be recalling some other arrangement of amino-acids. A recent examination of protein ...

Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that ...

Scientists now question how life’s building blocks first appeared before LUCA, reshaping our search for life beyond Earth.

Ancient evidence suggests a new twist in how we all got here.

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 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, ...

The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on ...
