Restriction enzyme - Wikipedia, the free encyclopedia

A restriction enzyme (or restriction endonuclease ) is an enzyme that cuts double-stranded or single stranded DNA at specific recognition nucleotide sequences known as restriction sites. Such enzy...

Restriction Enzymes - Background

These restriction enzymes generally have names that reflect their origin--The first letter of the name comes from the genus and the second two letters come from the species of the prokaryotic cell from which they were isolated.

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 Digestion of DNA: Introduction

Restriction enzymes are enzymes isolated from bacteria that recognize specific sequences in DNA and then cut the DNA to produce fragments, called restriction fragments. Restriction enzymes play a very important role in the construction of recombinant DNA molecules, as is done in gene cloning experiments.

Molecular Biology: How Do Restriction Enzymes Work?

Like all enzymes, restriction enzymes are highly specific. They cut DNA only within very precise recognition sequences. Study the illustrations below to see three different recognition sequences. The red line shows where the enzymes will cut the DNA.
