title: Alternating one-letter symbols for the representation of codon variations at the level of amino acid sequences.
abstract: An idea is presented to use different letter types (e.g. L. 1, L, 1, L, l) for the alternating triplets coding the same amino acids. Such compact and demonstrative amino acid sequence comparisons can make easy the identification of differences at the DNA level if not seen in amino acid sequences (e.g. for choosing specific or non-specific primers for polymerase chain reaction).
