... Why are there three nucleotides in the code? There are four bases in DNA (adenine, guanine, thymine and cytosine). Clearly, it is not possible to have one base coding for each of 20 different amino acids. Similarly, using two bases would be insufficient (4n or 16 permutations of two bases, where n = ...
