Explanation:
Restriction enzymes basically used in genetic engineering. Particularly in recombinant DNA technology. Restriction enzymes have two properties, which are very much useful in recombinant DNA technology.
First, they cut DNA into fragments or small pieces. This cutting is done to make the size of the DNA into a suitable one for cloning purposes.
Second, many restriction enzymes make staggered cuts that create single-stranded glutinous ends. These ends are favorable to the formation of recombinant DNA.
