Solution:

The restriction endonuclease enzyme inspects the length of a sequence. Once it recognises specific sequence, it binds to the and cuts each of the two strands of the double helix at specific points in their sugar phosphate back bone. Special sequence in the recognised by restriction endonuclease is called palindromic nucleotide sequence. Restriction endonuclease enzymes are also known as molecular scissors or biological scissors or chemical knives or chemical scalpels.
