What are the uses of restriction enzymes in biotechnology. Like all enzymes, a restriction enzyme works by shape-to-shape matching. When it comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the DNA molecule.. Each restriction enzyme recognises a different and specific recognition site, or DNA sequence., A recombinant plasmid is an example of use of a bacterial cell. The way we get to it does involve viruses, but indirectly; the restriction enzymes used to produce the recombinant DNA come from the.

What is a RESTRICTION ENZYME? A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.. More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. In live bacteria, restriction enzymes function to defend the cell against invading In bacteria, restriction enzymes protect the host organism against viruses by cutting up—restricting—invading viral DNA. The bacterium modifies its own restriction sites (by methylation) so that its own DNA is protected from the action of the restriction enzyme(s) it makes.

Basically, the enzyme will chop DNA into much smaller pieces which pose little danger to the cell.

A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites. [1] [2] [3] Restriction enzymes are one class of the broader endonuclease group of enzymes.
