Welcome to RestrictionMapper - on line restriction mapping the easy way. Maps sites for restriction enzymes, a.k.a. restriction endonucleases, in DNA sequences.

Restriction mapping is defined as a physical mapping technique used to determine the relative location of restriction sites on a DNA fragment, resulting in a restriction map.

A restriction map is a map of known restriction sites within a sequence of DNA. Restriction sites are sites on DNA where restriction enzymes, can cleave the DNA at or near the site.

Restriction enzymes cut DNA molecules at specific recognition sites. Restriction mapping involves digesting an unknown DNA segment with restriction enzymes and analyzing the fragment …

Restriction mapping is a method used to map an unknown segment of DNA by breaking it into pieces and then identifying the locations of the break points

The restriction/modification system in bacteria is a small-scale immune system for protection from infection by foreign DNA. In the late 1960's it was discovered that E. coli contains enzymes …

We assume that the multiplicity of a repeated fragment can be determined, i.e., multiple restriction fragments of the same length can be determined (e.g., by observing twice as much …

Restriction maps A map showing positions of restriction sites in a DNA sequence. If DNA sequence is known, then construction of restriction map is a trivial exercise. In early days of …

Jul 19, 2025 · To make things even clearer, this video tutorial explains restriction mapping with similar examples and stepwise logic. Sometimes watching a concept unfold visually can add a …

Restriction Map accepts a DNA sequence and returns a textual map showing the positions of restriction endonuclease cut sites. The translation of the DNA sequence is also given, in the …
