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 ...
Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...
