A description of restriction endonuclease cleavage sites within a piece of DNA. Generating such a map is usually the first step in characterizing an unknown DNA, and a prerequisite to manipulating it for other purposes. Typically, restriction enzymes that cleave DNA infrequently (e.g. those with 6 bp recognition sites) and are relatively inexpensive are used to produce at a map.
