It's not the restriction enzymes that are studied, its the DNA. The enzyme cuts or "restricts" the DNA strand at a known sequence of nucleotides. Different enzyme, different sequence.
For a Biomanufacturing application, where we want to insert foreign DNA, the gene of interest is cut and spliced with a restriction enzyme into a recombinant plasmid, transformed into a bacteria, and sent merrily on it's way to make Insulin, or whatever.
With an unknown piece of DNA (a functional gene that makes a protein of interest or is being studied), the plasmid has "restriction sites" or nucleotide sequences, for several restriction enzymes, all of which I have mapped out. The unknown piece of DNA is cut at each end by a single restriction enzyme and inserted into the plasmid, which gives me some landmarks. I insert the plasmid into a bacteria, grow a culture so the bacteria makes many millions of copies of the plasmid, extract the plasmid, and run an experiment called a restriction digest.
The restriction digests are a series of reaction with single enzyme and combinations of two and three enzymes, all cutting the plasmid at different nucleotide sequences. Then I run an agarose gel electrophoresis, which separates all the different pieces of DNA by size, and do an analysis called a Restriction Map. This counts the DNA fragments and their sizes, which enzyme and combination of enzymes produced which sizes and how many fragments, which enzyme cuts where, which cuts were definitely in the known part of the plasmid, which were probably in the unknown DNA, adding up nucleotide sequence numbers to make sure different mapping guesses agree, etcetera, etcetera, and so forth. Until at last, a map of the size and restriction sites of the unknown DNA insert into the known plasmid vector is deduced. This used to be done by hand, but there are computer programs that do it now.
This is Research, the Technology is down the line a few steps when the gene has been characterized, the protein produced has been characterized, the trials are done, and the restriction enzyme to insert the gene into the bacteria for Bioman has been established
Because these enzymes cut the DNA molecule at a particular site. But like scissors these are useful tools in genetic engineering or recombinant DNA technology.
When producing a recombinant plasmid, the plasmid and foreign DNA are cut with the same restriction enzyme(s) to generate complementary sticky ends for ligation. Using different restriction enzymes would create incompatible ends that cannot be ligated together effectively, making it difficult to form a functional recombinant plasmid.
A restriction enzyme (or restriction endonuclease) is an enzyme that cuts double-stranded or single stranded DNA at specific recognition nucleotide sequences known asrestriction sites....................refer in this website en.wikipedia.org/wiki/Restriction_enzyme
You use the same enzyme inn order to get the same restriction and binding sites.
A recombinant enzyme is an enzyme that has been produced through genetic engineering techniques by inserting the gene encoding the enzyme into a host organism, such as bacteria or yeast, to facilitate its production in large quantities. These enzymes often offer improved stability, efficiency, and specificity compared to their naturally occurring counterparts.
Restriction enzymes are the substances required to cleave the vector DNA during recombinant DNA technology. These enzymes recognize specific DNA sequences and cut the DNA at specific points, allowing for the insertion of foreign DNA fragments.

A Sticky End, referring to Biology is recombinant DNA. After DNA has been cut by a restriction enzyme it has "sticky ends" or recombinant DNA at the ends.

DNA fragments with specific sizes depending on the recognition sequence of the enzyme. This process is used in molecular biology to create DNA fragments for analysis, manipulation, or recombinant DNA technology applications. The resulting fragments can be visualized on an agarose gel.
These sticky ends, if they two pieces match, they will join together to form a recombinant DNA.

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.
Such an enzyme is called a restriction endonuclease
The first practical use of a restriction enzyme was in the production of recombinant DNA in the early 1970s. Scientists used the restriction enzyme EcoRI to cut DNA at specific sequences, allowing them to splice together DNA fragments from different sources. This innovation enabled the development of genetically modified organisms and the production of insulin and other therapeutic proteins. The ability to manipulate DNA in this way revolutionized molecular biology and biotechnology.
