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 ...
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 ...
