A good article, including a excellent history about the coding of DNA and how the '...approach may allow inroads into many additional unresolved questions: Why 20 and only 20 standard amino acids? Why are some amino acids assigned six codons, whereas others have just one or two? Could this pattern have anything to do with minimizing error? Cracking the code has proved merely the start to understanding its meaning.'
