MCQ
What is the function of the polymerase chain reaction in genetic engineering?
- ACut DNA into many fragments
- BCarry DNA into a new cell
- CLink together newly joined fragments of DNA
- DMake 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'.
