GenBank is a plaintext format for storing DNA data as character sequences.  It is a popular interchange format for molecular biology software.

It is the DNA encoding format used by the U.S. National Center for Biotechnology Information (NCBI).

The commands Import and Export support this format.

The GenBank format employs the following standard IUB/IUPAC conventions for encoding protein or nucleic acid sequences as alphabetic characters.

In addition to codes specifying particular nucleic acids or amino acids, the convention supports codes for ambiguous sequences where a position may be occupied by more than one possible nucleic acid or amino acid. For example the code R matches either adenine (A) or guanine (G).
