Answer

  1. Make millions of copies of a specific segment of DNA

Explanation:

Polymerase Chain Reaction is a method widely used to make many copies of a specific DNA segment. Using PCR, a single (or more) copy of a DNA sequence is exponentially amplified to generate thousands to millions of more copies of that particular DNA segment.

So, the correct option is 'Make millions of copies of a specific segment of DNA'.
