A sequence in FASTA format consists of a single-line description, followed by lines of sequence data. The first character of the description line is a greater-than (\'>\') symbol in the first column. Sequences are represented in the standard IUB/IUPAC single letter amino acid and nucleic acid codes, with a single hyphen or dash being used to represent a gap of indeterminate length; in amino acid sequences asterix (\'*\') can represent a translation stop.
