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 ...

Replacing one unit of a triplet code with another nucleotide yielded a ... The language of DNA was now understood and the code could be expressed in a chart. In 1968 Nirenberg won the Nobel Prize in ...

How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As ...
