How can the four bases that make up DNA specify the 20 amino acids that make up proteins? Clearly, each base cannot specify a single amino acid, as this would require at least 20 different bases.

Right away, researchers knew that the genetic code was more complex than one nucleotide per amino acid.After all, if this was the case, a person's DNA could only code for four different amino ...

The goal was for the model to make up entirely new amino acid sequences that, when formed in a cell, ... "Now that we know ...
