New chemistry hints the first genetic code wasn’t built from the same 20 amino acids
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 say a core assumption about the origin of life may be wrong
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, ...
Using quantum chemical methods, a team of researchers led by Dr. Matthias Granold and Professor Bernd Moosmann of the Institute of Pathobiochemistry at Johannes Gutenberg University Mainz solved one ...
With only rare exceptions, every organism constructs proteins from just 20 building blocks called amino acids. Recently, however, researchers modified Escherichia coli bacteria so that the ...
Membrane proteins play important roles in health and disease, but they are so hydrophobic that they require detergents to maintain their shape outside membranes. That makes them difficult to study.
