(c) molecular knives for cutting DNA at specific sites.
Explanation:
Restriction endonuclease cleaves DNA duplex at specific points in such a way that single stranded free ends project from each fragment of DNA duplex called sticky ends. These sticky ends can join similar complementary ends of DNA fragment from some other source.
