They can cut DNA at specific sequences.

Explanation:

Restriction endonucleases are enzymes that can cleave DNA to specific sequences or restriction sites.

For DNA insert to be clone, it must be treated with two restriction enzymes that can form compatible ends.

One of the enzymes must be a sticky end cutter which cut the two strand of the target DNA which create a 3 or 5 overhangs of 1 to 4 nucleotides. Restriction endonucleases can cut DNA at specific sequences.

Restriction endonucleases are useful in gene cloning because, as the name implies, they can cut the DNA strand at specific sites and sequences.
