Questions & Step-by-Step Solutions

Which technique is used to amplify DNA segments?
Correct Answer: Polymerase chain reaction (PCR)
  • 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 a method used to amplify DNA.
  • Step 3: Know that PCR involves repeated cycles of heating and cooling to separate the DNA strands and then copy them.
  • Step 4: Recognize that PCR uses special enzymes called DNA polymerases to help create the new DNA copies.
  • Step 5: Conclude that PCR is the main technique used to amplify specific DNA segments.
