What is the primary purpose of the Polymerase Chain Reaction PCR in molecular biology?

  • A: To separate DNA fragments by size.
  • B: To amplify specific DNA sequences.
  • C: To determine the sequence of an entire genome.
  • D: To produce recombinant proteins.

Explanation

The Polymerase Chain Reaction PCR is a powerful molecular biology technique used to make millions to billions of copies of a specific DNA segment. It is widely used in genetic fingerprinting, disease diagnosis, and various research applications where a large amount of a particular DNA sequence is required.
