Soon after the completion of the Human Genome Project, it became clear that the approximately 20,000 DNA fragments identified as protein-coding sequences were woefully inadequate to account for the ...

Researchers reveal how the presence of bulky aromatic amino acids at positions 1 and 3 of the aromatic/arginine selectivity filter determines urea and boric acid permeability in Aquaporin 10 paralogs.

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 ...
