Scientists use restriction enzymes to cut DNA molecules and ligation to paste DNA fragments together.

Scientists use high temperatures to separate strands of DNA molecules during polymerase chain reaction.

Answer 1

Scientists use restriction enzymes to cut DNA molecules and ligation to paste DNA fragments together.

Explanation: Restriction enzymes make specific cuts in DNA, producing compatible ends, and DNA ligase joins those fragments to form recombinant DNA molecules.
