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 endonuclease
An endonuclease cuts double stranded DNA by binding to specific sites, in many cases arranged in palindromes.
restriction enzymes A series of enzymes that attach to DNA molecules at speci?c nucleotide sequences and cut both strands of DNA at those sites. A bacterial enzyme that cuts DNA at a specific recognition sequence.
Restriction enzyme, endonuclease: A protein that recognizes specific, short sequences of DNA and cuts at those sites. See also Restriction enzyme cutting site.
restriction endonuclease - aka restriction enzyme - bacterial enzyme that cuts double-stranded DNA at a specific sequence.
Restriction endonucleases, (restriction enzymes) Bacterial nucleases which cut double stranded DNA at specific sites defined by short (4- 10bp) usually palindromic sequences.
Restriction endonuclease (enzyme). A class of endonucleases that cleaves DNA after recognizing a specific sequence, such as BamH1 (GGATCC), EcoRI (GAATTC), and HindIII (AAGCTT). Type I.
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.
