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 ...

For example, it did not yield any amino acids containing sulfur, despite the element being abundant on early Earth. As a result, sulfuric amino acids are believed to have joined the code much later.
