"The sticky ends of fragmented DNA are joined with vector DNA."

Explanation: Recombinant DNA typically is made by cutting both the gene of interest and a vector (e.g., a plasmid) with restriction enzymes to create complementary "sticky" ends, then ligating those ends together with DNA ligase so the fragment is incorporated into the vector.
