DNA Amplification

DNA amplification is a process that makes many copies of a specific DNA segment. It uses a technique called Polymerase Chain Reaction (PCR), where the DNA is heated to separate the strands, then cooled so a special enzyme called DNA polymerase can build new strands by adding complementary nucleotides. This cycle repeats multiple times, doubling the amount of target DNA each time, resulting in millions of copies. This method allows scientists to analyze or detect small amounts of DNA from samples like blood, hair, or saliva efficiently and accurately.
