A highly specific 'active site'.
TaqI's restriction site is:TCGAAGCT
By playing with you.
You use the same enzyme inn order to get the same restriction and binding sites.
Effect
restriction enzymes
Such an enzyme is called a restriction endonuclease
TaqI's restriction site is:TCGAAGCT
Restriction enzyme cuts DNA strand at specific locations Restriction enzyme cuts DNA strand at specific locations

Topoisomerase is not a restriction enzyme but an enzyme that keeps unwound DNA from tangling while it is being replicated.
Restriction enzymes are produced by bacteria to help destroy foreign, invading DNA, such as the DNA of bacteriophage (a virus that infects bacterial cells). Every restriction enzyme comes with a methylase enzyme, or more specifically, a DNA methyltransferase. The methylase enzyme methylates (adds a methyl group) to the restriction endonuclease site on the cell's own DNA, which protects the sites from the restriction enzyme so that it does not degrade its own DNA.
You use the same enzyme inn order to get the same restriction and binding sites.
