Q: Which of the following techniques is used to amplify DNA?

Solution: Polymerase chain reaction (PCR) is a technique used to amplify specific DNA sequences, making millions of copies of a particular segment.

Steps: 4

Step 1: Understand that DNA amplification means making many copies of a specific DNA segment.
Step 2: Learn about the Polymerase Chain Reaction (PCR) technique, which is commonly used for this purpose.
Step 3: Know that PCR involves repeated cycles of heating and cooling to separate DNA strands and then copy them.
Step 4: Recognize that PCR can create millions of copies of a specific DNA sequence quickly.
