Using just 20 amino acid letters, ribosomes spell out all the proteins needed to keep cells ticking. But Jason Chin, head of Cambridge’s Centre for Chemical & Synthetic Biology, has long wondered ...
Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...
The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...
