Actually A, T, C, and G represent nucleotides.  DNA and RNA 
themselves are nucleic acids.

Agreed.

It would be more compact, since a one-letter amino acid 
abbreviation (ACDEFGHIKLMNPQRSTVWY) represents (ln 20)/(ln 2) = 
4.3 bits rather than the 2 bits a nucleotide (ATCG) represents.

Of course, thinking of proteins as encoding something is a 
little stranger than thinking of nucleic acids as encoding 
something.
