Q
Q: Which technique is used to amplify DNA?
Solution:
Polymerase chain reaction (PCR) is a technique used to amplify specific DNA sequences.
Steps: 5
Show Steps
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 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 requires specific ingredients like DNA, primers, and a special enzyme called DNA polymerase.
Step 5: Realize that after several cycles of PCR, millions of copies of the target DNA can be produced.
