Codons are three letter words: 64 in number.
Explanation:
Just consider this: there are four bases i.e. four letters in genetic language. Now if you want to make two letter words (i.e. codons) using the four, you get only probable 16.
These will be insufficient to represent all the 20 naturally occurring amino acids.

the only nitrogenous base that gets changed is thymine (T). all other bases stays the same, unless mutation happens. plus rna contains only one side of the molecule, because of DNA polymerase.
