IUPAC system for nucleotide nomenclature

IUPAC system for nucleotide nomenclature

Using the International Union of Pure and Applied Chemistry (IUPAC) system for degenerate bases (Table 1) we can insert a single-letter code to represent our unknown region. In the above example we would use ‘S’ in place of GC, and ‘V’ in place of AGC.

Easy to memorize!
