Restriction enzymes identify short DNA sequences
A restriction map shows the positions at which specific short base sequences (i.e. restriction enzyme recognition sites) occur in a DNA molecule.
Restriction Enzymes
Restriction enzymes are DNA-cutting enzymes found in bacteria (and harvested from them for use). Because they cut within the molecule, they are often called restriction endonucleases.

Restriction Enzyme
A restriction enzyme is an enzyme isolated from bacteria that cuts DNA molecules at specific sequences. The isolation of these enzymes was critical to the development of recombinant DNA (rDNA) technology and genetic engineering.
Restriction Enzymes: Microscopic Scalpels
Isolated from various bacteria, restriction enzymes recognize short DNA sequences and cut the DNA molecules at those specific sites.

Restriction enzymes
Restriction enzymes were discovered in bacteria. Bacteria use them as a defense mechanism to cut up the DNA of viruses or other bacteria.
Restriction enzymes Endonuclease enzymes that recognize specific base sequences in double-stranded DNA and cleave both strands of the duplex at specific places.
Restriction enzyme cutting site
A specific nucleotide sequence of DNA at which a particular restriction enzyme cuts the DNA. Some sites occur frequently in DNA (e.g., every several hundred base pairs), others much less frequently (rare-cutter; e.g.

The use of restriction enzymes and then ultimately PCR, all of these methods that underlie the recombinant DNA revolution were critical to being able to make maps of the Y. Initially, our first coherent maps of the Y came together in the 1980s.
DNA insert and vector molecules are digested with two different restriction enzymes to create noncomplementary sticky ends at either end of each restriction fragment.

Restriction
The cleavage of double-stranded DNA by an endonuclease (restriction enzyme). The restriction enzyme distinguishes between self and foreign DNA based upon the modification of its DNA-binding site (for example, by methylation).
Restriction endonucleases, (restriction enzymes) Bacterial nucleases which cut double stranded DNA at specific sites defined by short (4- 10bp) usually palindromic sequences.
Often due to the presence of a restriction enzyme cleavage site at one place in the genome in one individual and the absence of that specific site in another individual. See also variable-number-of-tandem-repeats (VNTR) locus.
