Explanation:

PCR (Polymerase Chain Reaction) is a laboratory technique used to amplify (make many copies of) a specific segment of DNA. Separating DNA fragments is typically done by gel electrophoresis. Isolating DNA from a cell involves cell lysis and purification steps. Cutting DNA into small fragments is usually achieved by restriction enzymes.

Answer:

make many copies of a DNA fragment.
