Restriction enzymes are used to cut up DNA into fragments with 'sticky ends'. It allows for the gene of interest to be isolated. A plasmid can then also be cut with the same restriction enzyme and the sticky ends are spliced together with DNA ligase. The recombinant plasmid can then be put into new host cells via a variety of methods.

Restriction enzymes cut DNA at sites called restriction sites on the DNA. These restriction sites are specific sequences of 6 - 8 nucleotide bases. Restriction enzymes can be used on all types of DNA. If the DNA is cut by a certain restriction enzyme, then we know that the DNA contained the restriction site. This sort of an experiment is called restriction site analysis
Restriction enzymes are used to fragment DNA by cutting it at specific recognition sites. These enzymes are naturally found in bacteria as a defense mechanism against foreign DNA, and are commonly used in molecular biology techniques like restriction enzyme digestion.
Restriction enzymes, also known as restriction endonucleases, are used to cut DNA into smaller fragments. Restriction enzymes are found in bacteria, where they act like molecular scissors by cutting up DNA from invading viruses or bacteriophages. Each restriction enzyme recognizes a specific nucleotide sequence and cuts the DNA at that site. This process makes restriction enzymes extremely useful in biotechnology where they are used in procedures such as DNA cloning, DNA fingerprinting, and genetic engineering. There are hundreds of known restriction enzymes, and each one was named for the bacteria from which it was isolated. For example, EcoRI was isolated from Escherichia coli and HaeIII from Haemophilus aegyptius.
Restriction enzymes and DNA ligase are necessary to make recombinant DNA. Restriction enzymes are used to cut the DNA at specific sequences, while DNA ligase is used to join together pieces of DNA from different sources.

Restriction enzymes are not typically used in PCR. PCR relies on DNA polymerase to amplify specific DNA sequences, while restriction enzymes are used to cut DNA at specific recognition sites for other applications, such as cloning.

Restriction enzymes originate from bacteria.
Enzymes called restriction endonucleases are used to cut the DNA chain at specific recognition sites. These enzymes recognize and cleave the DNA at particular sequences, allowing new genes to be inserted at the site of the cut.

Two different restriction enzymes commonly used to cut the pUC19 plasmid are EcoRI and PstI. For cutting the lux gene DNA, the restriction enzymes commonly used are NcoI and HindIII.
